I'm starting to think that a MTB FD is my best solution.
You may need to move the spacer from the drive side to the non-drive side since the spindle is a fixed length. You might also try a slightly thinner spacer. If you are only a little way away from not rubbing, a thinner spacer could move it just enough.

Before you tear things apart, take a look at the range of motion and alignment on the Tiagra. You said that the derailer rubs in the larger gear. Can you move the derailer outboard by hand? If so, then it's a cabling issue. Also check to see that the derailer is properly aligned with the crankset.
