For player sprites, it's highly unlikely - hand-drawing animations is a ton of work, particularly for player sprites because of all the different poses they have, as well as the equipment they can use. Due to Flash limitations, I also have to link them into the main game file, which would make the entire download larger. That and it wouldn't really help gameplay unless it comes with a fundamental different story line or mechanics, all of which is utopian when I'm still working on the main story line.
For monsters, eventually. However, I'll animate monsters as I make the content I have planned, so they'll have to fit with that. ;P I don't do art requests, so if you want to see a specific monster, you have to draw and animate it yourself (in which case I can put it in if I get copyright clearance).
