So, say you're a player starting with a messenger monodrone. Your abilities are flight, being little, and being able to deliver recorded messages. You fight with a fine crossbow, and steal shit from people.
Advance a level, and now you're a tridrone. You have stability thanks to three legs, and multiweapon fighting with your three arms. You're also small or medium-sized, and better armored. You don't fly anymore, because you lack wings or gas propelants.
Advance a level, and you're a duodrone. Either you can fly again, or you specialize in TWFing with bows.
You see my point? There isn't much continuity. They actually are completely separate races which happen to have some stuff in common, just like the demonic tamari.
It could work. I mean, I can imagine a mordron, having gained new experinces, goes dormant for a minute. Then there's a great clanking noise and it starts spinning around and steaming, and then a new polyhedron appears in its place. That's even kinda cool.
The problem is that, in a normal game, you're basically playing a different character each session.
