they're not really mixing materials. the tail is a stand alone unit that
caries its own loads so there is no real strain mixing - the loads are in
different directions. it's just point bonded to the tail. also sometimes
it's ok to put a little glass on top of a carbon part, but rarely a little
carbon on top of a glass part (is this partiality?).

if you do decide to beef up the tail end , follow Martin's drawing and parts
list. Martin did the FEA for the Lancair 320 and would have recommended
carbon if he thought it best, so that weight could be saved. I am in the
very same boat as your friend on retrofitting the tail and trying to figure
out how to keep the tail light(the third owner of a veery old kit).
