BRP Skills Level Advancement for GURPS

[Moebius]

For the last several months I've been doing a lot of game system research of sorts. I've visited True20, Savage Worlds, Pathfinder, WEG's D6 system, etc. For a long time I believed the Chaosium Basic Roleplaying System was the one for me. Eventually that infatuation died down, and I've recently fallen in love with GURPS again. I've been loving what I've seen in the Lite booklet. We'll see if it sticks.

In the meantime, I was left with some aspects of the BRP system that I really like. The character advancement system was probably the coolest part of the rules, IMO. Can this work for GURPS? I can monkey around and try to come up with something, but I'd rather not reinvent the wheel if a variant or home-brew system is already out there.

BRP is a d% roll under system. Basically, if your character attempted and succeeded to use a skill during play the player would put a check by that skill. At the end of the session the player rolls d% for each checked skill, trying to roll HIGHER than the skill level. If they do, they get to raise the level. Something like that.
