I'd like a set with full bottom row minus space, both shifts, tab, enter, backspace, and maybe Esc. If all those match, then the edit and numpad keys can be original cherry and still match well.
So, an all faux cherry kit could work, but I think the keys I mentioned make the best cherry supplement kit for matching cherry keys on modern boards. Both shifts would match, and all the alpha cluster caps with words would be consistent. The "Oqsy kit" would be expensive, tho. More setup fees for several keys. It would take a decent sized buy to be worth it. From then on they'd have the templates tho. Food for thought.
