Hi!
First of all - welcome to GH! GMK 9009 and 9009 is a beautiful classic keyset that is adored by many and for a reason - timeless and just the right amount of pop and professional.
Mmm, I haven't looked around for a blank 9009 keyset or alpha-numeric keys but if you're fine with not having proper Hungarian characters on the keyset, you're best bet would be either search for a GMK 9009 in the aftermarket or go with something like EPBT 9009. And it actually has an international set so maybe there's appropriate key caps your language uses.
Unfortunately that's not an option for multiple reasons. We use a QWERTZ format, so the Z/Y most likely has the wrong shape, and we have dedicated keys for our special characters(ÍÖÜÓŐÚÉÁŰ). We also have different key combinations(Ex.:@ is AltGr+V).
I've given up on getting my hand on a Hungarian PBT, because it just isn't going to happen, but not long after posting I found a topic here with a guy selling blank GMK caps, so most likely I'll be able to figure it out.
BTW, as a hungarian, I know it is pretty hard to get even low quality keycaps with hungarian legends and sublegends. It is nearly impossible.
I've came across once a replacement set, Cooler Master sells hungarian localization keycap sets, but sadly, they're laser engraved painted ABS. Luckly, they're pretty cheap, and use OEM keycap profile. Link to a hungarian webshop where you can buy them:

It's not that hard, and if you have an ISO keyboard you can type everything as usual, but if you have ANSI, you lack the letter í. But it is not a big deal, Alt Gr+J to type í , and Alt Gr+I to type Í . It's not that hard to get used to it, and when you type bindly, the lettering doesn't matter at all.
