Rig custom UI

Howdy,

I started a couple days ago on a project to make a custom bip rig setup basically. What i'm going to try and do is make a plug-in basically for max 9. It'll work just like a biped does now, but be more controlled like a bone setup with a scripted UI with constraints and all that goodness. This biped will be universal so I can setup however the character is shaped and how tall or wide it is. The only thing you'd have to do is skin the model basically. Before I get too heavy into the project though I wanted to ask, do you think this is possible?
