I need you to help me replace my current keyboard, which is Logitech k750. I wanted to go with mechanical switches this time...just because.

From what I have read and switches I've bought and tested I *think* I'd like to go with low profile tactile or linear switches (haven't decided yet but leaning toward tactile), so Kailh PG1350 comes to mind. If you know some others like that I could also take them into consideration. The lower the travel (especially pre) the better. I know there is PG1232 series...somewhere...but those are only clicky at the moment as far I've seen, even though Deskthority's wiki says they are tactile - or maybe I'm wrong and wiki is right?
But the problem is I need a full keyboard with ISO 102 physical layout (based on Deskthority's wiki - basically big enter and backspace) and international logical layout - I'm from Poland and we don't use region specific layout here - the one I'm using looks like US one with AltGr I think and it's called Polish Programmers, like this one:

Also this layout would be more then fine:

I've seen keyboards like Tesoro Gram XS, Dareu EK820 or Havit HV-KB395L and they are beautiful but they lack the layout.
I don't care about backlight. I don't need it.
I do care however about multimedia keys - I often use them to control Spotify and to mute sound. Could be as a Fn shortcut but dedicated are more then welcome.
Is there a keyboard that will meet my requirements?
And there's also this small thing I would really like to have which is wireless. I do play a lot of games so it can't be anything that will add too much latency (Bluetooth). I did check Logitech's G613 but it is big and didn't feel right to me for some reason. But my perfect keyboard would be Logitech G613 with low-profile switches.
I know the probability of finding keyboard like that is very small so I also wonder if it's possible to build one.
I tried to find some components but I'm noob here - I don't know where and what circuit board I should choose, don't know anything about controllers and where to get a case. The wireless is something I could let go but with very heavy heart mind you.

um...help?
