Machined a D-shaped 'shim' with a 27.2mm dia. blind hole in it, as deep as necessary to get the required seatpost extension with the shim all or mostly in the frame. Bond your seatpost into this 'shim' then clamp the shim in the frame. Probably heavy, and wouldn't be too cheap either for a one-off, but it should work.
Also, who would you recommend me going to in order to get something like this done?
Discuss light weight issues concerning road bikes & parts.
another approach you might consider is to buy the frame/bike, cut a hunk off the bottom of the seatpost and have a machinist hogg out the inside of it to 27.2. Then bond it to your new post in the appropriate position so that you can actually clamp it.
