Here for 24 hours and your already ruining my plans haha.
Well replace the obvious enemies were not going to use (Yakra/Zombar/Giga Gaia etc). Just have them point to the Azala and change the pallette.
Taking a quick look at Chrono Tweaker it seems like if you change "sprite starting location, SPrite assembly, Sprite Size etc, to the same as Azala we would have 3 enemy Azalas that we could play with the pallettes of.
I do want to have a dark crono fight though...
