They're good ideas, but I don't think they would work.
Let's get the player models out of the way first.
Doesn't this player model look a bit too complex for Blockland standards? And it doesn't fit with the blocky theme.

Also, it isn't that difficult to make the default player model slightly resemble a Toon. Trust me, I've done it before. I used to host a Boss Battles server, and Flippy was one of the playable bosses. Out of the 5 or so people who joined the server and actually knew who Flippy was, they thought it was pretty accurate.
As for the gags, I'd definitely like to see those happen. But how would Toon-up work? And Trap? Lure? Sound? Drop? Pretty much only Throw and Squirt are do-able without some weird workarounds.
