Don't forget about the fact that the EF is still in devlopement, more precisely it's systems are. It's still a long way to go until the desired multi or swingrolecapability will be achieved. But the primary task right now is QRA, aerial combat. And allthough the radar may be not at it's final stage (i think most of them still have no aesa) it performs very well in this role. (in simulated combats at alaska flag they managed to shoot down some raptors 
)
I must admit that i don't much about the slovakian airforce and the current shape of it's migs but the purpose of modernizing the planes to natostandards is not that bad because it allows interaction with other flights regardless if they are migs or falcons or others, as long as they are also nato certified. We don't know if a new war will break out or what the coalitions will be then but it is highly expectable that the whole europe (yes even the british ) will be on the same side of the curtain and therefore should interact with each other as smooth as possible.
I see where you come from if you say that you would like to see a focus on the Hinds but that would neglect a mainpurpose of an airforce and thats Airpolicing. So you need a plane which can get asap to an unidentified contact, vis ID it and force it to land/ engage it. A Fulcrum is quite a good plane for that task, i mean it was designed exactly for this role
I don't know if it would be really much cheaper if you would let czech or polish fighters stay at your bases and assign this task to them.
Again, i don't know much about your airforce or your financial status quo. (but i'm quite interested, so tell me what you know 
)
... OH SO .... no, the mils was for real ground-support use thought (better effectiveness when fighting in our country-relief), while the migs would go to the joint air defense (so there wouldnt be 100 planes in all our joint-countries, but around 20 and really duty-able and cost effective) : P .... as the modernization NATO standard - i meant the fact, that the concrete ways of sending information between units isnt much orderly. So as for the US or RF is the need to just clics few buttons in the mig to say the ground units what kind and where some enemy is (sent right trough Isys. - max 2 transfer-points) we would have to say first our command, than to the main HQ, than to allied HQ and they would send this to theyr units ... cause the electronics still have some special signal inf. characteristics for some counties (former soviet ones that is). That would need a complete unification in Inf. gear between US-GB-FR-GER and then enforced upon all members .. that will come, but has some steps and economic crisis to overcome ... in short, yes, we have the MOKKYS to do it the few clicks way as it should be for a 21st century world, but the old vehicles are not capable - and it takes a lot of time to change them/buy new ones - firmly my sight of that happening is around 2030-2040 in SVK. If economics get better at all in Europe.
... as for the geopolitics, i dont like to say that, but the political sphere doings doesn't have to mean our people like much what NATO does (that is whyte our passive aproval - and so we are taken as responsible for it de-facto too), and as the fact, that we have no expert leaders nor any real policy in it - not to mention the pitifullnes of our word in the maters, i would not take us as pure and eternal friends. (dont mean civil. populations, we have really no reason to be foes, specially in drinking-habit terms whyte GB, so RF
). Lets just say, that we are, as many post-soviet republics in a state of total disinformation and real dis-belief of our politicians doings. So if something changes in the REAL democratic way, it may turn us out quitting EU and NATO for some principal issues (mainly UN/OSN non-permitted war playing around the world of some of NATOs main members // idiotic terms of specific trade and standards agreements in EU - wich are really destroying some of our home econ. sectors -- that points N. Fraage too, but not much specific that is). Long story tho .. better to discuss that at PMs and not walls.
As for the Mils - i am a fan of 24s and Su-25s, so its a heart thing too.
Yes, russians still have the radar for Su-34/35 and PakFa not ready, there are some complications in theyr microelectronics to do - mainly because theyr mil.-standards (should be fixed by max. two hammer hits
and run on all flammable stuff for fuel as the T-90s
) So i dont see the real capabilities even of nowadays RF radars to be public, nor in Mil-Sims before 2030.
But that is fine, cause till then OT will be finally out and the community will do a great job for models, world-building and systems-scripting.
We really need to prolong the human life a lot, i wont to live to see it come !!
