Question about lack of space for monster molds...

Hi!

I was wondering: in the whole battle screen i know that the space for drawing sprites is used from:
- 4 slots for characters, yet it's adapted to Magitek armor size, due to the situations in which you ride the M-tek armors, so it's a bit bigger;
- 128x128 for molds of monsters;
- An unknown size is assigned to when an esper animation is called... anyone knows how much is this space used? it should be greater than 128x128 because it wouldn't be enough to make Crusader fit in that space...;
- Some space is used from Sketch command too, probably another 128x128, since it's the greatest size of sprite you can sketch in the game(am i correct with the actual size used? )
- And i guess also for attack animations, battle command animations, event animations... how much space is used here?


I dunno if something else ask for space too, but the question is:
Let's say for example that we elimate the whole Sketch feature and the space used for it is free again... in that case would be possible to use it to have as max size for mold something like a 256x128? Basically double space for monster molds...
