I found useful to solve similar problems the coupling of two freely-available programs
called "DPS" and "NAP". You can try them out at http://gcg.tigem.it/cgi-bin/dps.pl
and see if they can solve your problem at least in part, then ask them
directly to the author !
Maybe I am naive, but you can solve this problem also with GCG FrameAlign,
setting the gap opening penalty to a suitable high penalty and gap extension to
0 .. give it a try ! ..
Ciao,
