Unicomp buckling springs keycaps with Russian/Cyrillic layout and two Geek Hack single unit keycaps.
I hope you post some pictures. I would  really like to see those keycaps!  
OK, so now it definitely in my post, as i brought it home today 

I thought there will be only keycaps, but no - I got all keys replacement set for 101-key layout (save for spacebar) - keycaps and stems. 
Stock keycaps were that uniform dull gray, so I aimed for something lighter. With golden Cyrillic letters and partially retained gray buttons...
Well, some pictures, as promised.
