What sort of sets would you want to see if this became a thing? Would you rather see Wario Land themed ones, maybe based on the first few games? Or WarioWare ones based on the casts' adventures in Diamond City?
My immediate thoughts is like those huge ass detailed LEGO city sets you'd have one for Kitchen Island and one for Diamond city so you got your big pieces for both series.
Golden pyramid and Wario's castle are obvious picks too, the toy box land from Wario Land 3 would be nice and so would a cute Halloweeny Ashley's mansion.
The electronic Wario would be funny to see him act all antagonistic if you put him near the bros or peach.
