I think it would be nice to have a new ride to ride for SITS pins and i think i have one that would be fairly doable.
I think the seven dwarves mine train ride would be great to add in as a new SITS ride! And I already know the perfect place to place the entrance,snow whites hide and seek forest!
Alternatively, it could be a new game like how you added star commander as a new game and that would work well too! And the object of the game would be to collect as many diamonds as possible,kinda like the host event we had quite some time back for fantasyland(if i remember correct) that was basically this.
