So I had an idea; there could be a mod where, as VL perks accrue, the VL's powers could be gradually transfered to the regular form, too. Imagine if you could "bat-warp" in normal form (assuming of course you are a Vampire), get the powerful drain spell, etc? Each VL perk would have two effects basically; what it does now, plus unlocking a currently VL-only ability for use in normal form. With the whole tree filled up, there would be little to no reason to shift anymore besides visuals.
Obviously such a mod wouldnt be for everyone but I think it could be very cool. Im not sure I have the skills to make it happen myself so I thought I'd pitch the idea first and see if anyone wants to pick the mantle

Feel free to point out if you'd have any interest in this!
