how about a replay where tori has to build uke with gambling?
make 3 giant cups with the help of modding. break all of uke's joints with magic, and place them somewhere. then, pick three of uke's bodyparts and put them under the upside down cups, and scramble them (but show them to tori before scrambling). tori then has to pick a cup and guess which bodypart is under it, his objective being to rebuild uke correctly. for example, tori goes /em "I bet the head is under the cup in the middle", but he is mistaken and it is actually the foot that is under that cup. then, following tori's bad choice, the foot flies to the position where the head should be. then, introduce another different bodypart and put it under the empty cup, and scramble it again. in the end, you could have uke be a mess of joints and bodyparts in the wrong locations. you should make him wave and say hi, and have tori be somewhat horrified lel
or another idea, something similar to what i described above, but tori has to fight uke afterwards. so he would be attempting to intentionally pick the wrong bodyparts (in order to build a malfunctioning uke) but accidentally picks the right ones (or picks the wrong ones, but happens to create a really strong uke by accident)
and then fight him and stuff
