I'm doing the exact same thing so please let me know how your rebuild goes. I have an Ultegra groupset off an runined Planet X Alu frame and want to get a nice steel frame. I imagine the main issues will be, as you say 11/8th forks, but also maybe headset as steel frames mostly take old school quill stems, perhaps also bottom bracket and someone told me front mech (could be difficult to mount).

Very interested to see how you find the transfer.
