Some other ideas for Crash's FS:
-Some kind of giant Nitro/TNT chained crate explosion
-"Time Trial Run" - Crash grabs a golden clock and performs a rapid combo of shooting the opponent with his bazooka, sliding into them, tornado spinning into them upwards and jumping off of them, to replicate the experience of doing an extreme time trial run of a Crash level that involves successive skidding, crate bouncing-off-of and tornado spinning across crevices.
Also here's some fanart from a Japanese fan that wants Crash in...
