The limitation is that you're stuck with the keycap widths available in each row of a sculpted Windows-like keyboard. In the case of the CoCo keyboard I contemplated, I could not exactly match the widths of all of the non-1x1 key caps of the original keyboard, but I was able to come up with an alternate layout that I think would have been serviceable.

Maybe you can get some ideas from this (somewhat tasteless) project?
