Limits of homologization for phylogenetic analysis

I am coding morphology, mainly in two subfamilies of one beetle family.
The bursae copulatrix of both groups have sclerites, which appear
informative. I am confident about homologizing sclerites within each
subfamily, but not between them. So, I expect these characters to be
informative only for within subfamily relationships.
I would like to write an independent nomenclature and set of characters
for the sclerites of each subfamily. I would code the second subfamily
as "?" for the unhomologized characters of the first group.
Are there perils here of which I should be aware? Could you suggest a
reference on this subject?
