If you just want to change the "From" for the current request, that is fine.
I understand. Changing To/From by a proxy has long been a thorny
issue, in the sense that on the one hand those fields are purely
cosmetic in strict-3261 mode, but on the other hand, changing them
breaks 2543 compatibility, and it's just not something a proxy is
supposed to do.
I suppose that a very strict UA could also refuse to process replies
which contain From/To header values that do not match the ones it
sent, even if those values are not used for dialog or request
association or anything related to maintenance of state per se.
