Love this set idea!! I've been wanting to pick up an XDA profile set, and this is probably going to be it.
I know there will always be a million people asking for kits to be made and split and all that, but Ican't help but wonder how it would look with Mono legends for the top number row... especially with that iconic !. My boyfriend and I were just talking about that the other day, it was used in Japanese fonts for old games as well and is instantly recognizable. A full sized version would probably be awesome!
I did find the novelties a little underwhelming though. I understand it's very hard to create "on topic* novelties, and I thought the sword and shield were a nice touch, but I can't help but feel something is missing. As somebody else linked, you can already get "generic" sets similar to this. The profile and quality will definitely be better, but I'm trying to think about something that might set it apart. Unfortunately I'm not generally the creative type, but I'll know it when I see it!
I did like the idea of RGBY keys, but that might be outside the aesthetic of this set honestly, and I'm struggling to think of a place where you could pull them off while still maintaining a semblance of distinctive plus-sign shape.
Not sure how close to infringement this would run but you could always do the LoZ inventory items running up the numpad.
