[feature request] Randomised Enemy Graphics

[CaptainStalfoss]

I love The Randomizer, but have you ever considered the ability to randomly replace the graphics for various Sprites?

Reason i ask is because i already do this privately with my own Random runs.
I made a huge sprite sheet of various themes etc, uploaded here:

And while it isn't perfect, It certainly ads new flavor to the game.
