front derailleur clamp size

Is it possible to replace the integrated clamp of a
Shimano 105 derailleur with a bigger clamp? Or do I have
to buy a new derailleur when changing to a frame with a
bigger seat tube?

Thanks Tobias Franzen

Just went though this myself. You need a shimano oversize fd
adapter and braze on fd.
