Yeah, I've thought of doing this sort of thing, but it doesn't work as well as you'd think because people expect to be able to see their character, and if it's just a cloud of stuff it tends to look pretty bad. But there's a variety of things we can do along some of those lines, and also with literally transforming players into this or that. For instance, making them turn into a little blip and shoot forward or away for a second while doing a directional boost sort of thing. That way you can still "see" your character, but your character just became energy for a second, etc. Lots of ways we can do some pretty cool stuff!
