TFT Practice tool?

just wondering, would it be possible to make this a thing? all we need is the ability to use both grids for allies and enemies, ability to spawn any item and have unlimited gold/xp.

the ui could just be the same "damage dealt" graphs we already have. units could be upgraded by just clicking on them and pressing like crtl 2 (downgraded with crtl 1)

i feel like this could even be lots of fun for the community, they can build a comp with unlimited items, any number of units and challenge people to beat their setups. or even for streamers they could couch co-op challenges something like "tabs" (totally accurate battle simulator) does, and i feel while it may not be a complete game changer, it would be very neat to see such a thing in the game
