Relic Castle

Hello! So, I want to know if it's possible to resize the height and width of the game to allow larger battle front creature sprites to be used in the game. My game involves using very large boss sprites, and the current size does not support that, as well as summoning up to 5 creatures on the field at once on your team (3 boss aids and up to two creatures). And how to reposition battle sprites.

Also, how would I get following pokemon sprites working? Do they need to be a set size to be able to display and walk correctly in pokemon essentials, or does the following pokemon trainer script help, or... I need an example sprite, or something. And not a sprite that utilizes just 48x32 trainers, I already know that works.
