I do think that all of these skin changes is a wonderful idea. At the very least, it would bring life and reinvigorating joy to see new recall animations to these champions who would only then be even more worth getting. I do want to explore and provide some feedback on the ideas posted here.
Beginning with Corporate Mundo, one of my first thoughts was, "flips or breaks the table?". Should he do both at different intervals, perhaps as an RNG or alternating type mechanic? What if he did only one or the other removing one entirely? Instead of flipping the table, would it hurt if he always broke it? Or the same if he always flipped it? And which would be more appropriate? I could easily see him doing either, with different ideas and why he would either flip or break the table. My opinion is that he would be more likely to break it unless it was a fancy desk. I also really enjoyed the description of "Mundo stuff."
I wasn't going to post much on Surprise Party Fiddlesticks, but then I thought about the cake. I thought about how it was a lie, and then thought about, should it be a cake of either vanilla, chocolate, strawberry? Should Fiddle only summon one flavor of cake? Should he alternate? Which cake flavor would best represent Fiddle if he chose only one to recall with? Would there be a little summoning animation to herald the arrival of the cake? Despite all the questions, this animation plays out very well I imagine.
For Gentleman Cho'Gath, I would imagine that the table used in his splash art would be the table used for the tea cup and tea pot. Rather than posing many more questions, I would also recommend he sits, finishes the tea, then continues as you suggested. Maybe you implied it, but I just wanted to make sure.
It would be pretty exciting to see if these changes ever got made.
