I'm not really enthusiastic about studying a modified, localized version of Aikido. I want to experience the true Aikido. And it seems I have very low chance of meeting my goal in Ukraine.
I understand what you're saying, but the only way to experience the true aikido would be to have been a Japanese uchi deshi under O-sensei. All his students (and their students) modified aikido, so it wouldn't be true. And (imho) you would need to be Japanese as to not miss lots of the implicit and explicit cultural references made by O-sensei. (Forgetting for a moment that apparently even the Japanese uchi deshi often didn't understand.
So basically, I'd say see if the 2nd dan is any good, if he's actively trying to improve, check his lineage, see if his students are any good, if the atmosphere in his dojo is good and then make a decision. I mean, you can also see this as an opportunity to help mature aikido in Ukraine.
