I just don't see how this can be done. You will be pulling and pushing on the door at an awkward angle. You might call a local door service company and see if they have done this.

Current: 7' doors in a 12'11" garage.

I was staring at it this afternoon, and measuring heights, angles, weather stripping, etc.. and I thought that if I added two additional panels and move the whole opener and track up the additional 3' 8" (approx.) extend the track up (on the same angle or slightly less), replace the springs and remove the outside door release handle - so it doesn't hit the header - it should be able to pull the door up and back the same amount on the horizontal track - just leaving the last 4' or so vertical above the header.

As long as the springs are for the new door weight - I think it should work. And clearance under the door & opener should be fine for a lift with the upper car facing towards the door.

Okay I didn't realize you intended to increase the door height. It is doable then. You can purchase from Sears a rail extension kit for an 8 or 10 foot door.
