Are you still looking for requests? Because I've got something if you are. Could you make me a doom vending machine? And by that I mean, could you make me an imaginary rotom-v (vending) form? Design it however you like, but I think the trick would be to find a way to differentiate it from the similarly shaped rotom-f. Possibly a large plexiglass front panel displaying the soda bottles inside? IDK, its up to you. If you do display any soda bottles though, all I sell is diet dr pepper (someone asked me what I sold in chat once, I came up with this and I just stuck with it).
EDIT: Just wanted to make it clear, it doesn't need to have a plexiglass panel, I was just trying to provide an idea to help distinguish it from rotom-f. You do whatever you do.
