It's really up to you what you want to do with that. SA (row 3) and DSA keycap sets from Signature Plastics as well as XDA keycaps all have perfectly uniform heights, with no slope differences. If you want Colemak legends, that is a bit of a taller order and fewer sets have that, though some have "compatibility kits" for the homing keys. That is really the only obstacle to just moving keycaps around to get the printed layout.
I use blank keycaps, having been a touch-typist for years. This means that any keycap set with a blank option can be used without it looking weird. :) You could also go the less fun route and just leave it as QWERTY but type in Colemak. I suspect a lot of people take this path.
