I am referring to when TCP retransmission occurs it will in general collaps
and retransmit
not just the potentially small lost segment but a fullsize segment.

This retransmission will collaps multiple small RPC/NFS pdu's into one TCP
segment
regardless if they were sent in separate small segments or not.

Yes, it will happen for NBSS as well.  It will happen for everything running
ontop of
TCP since it is a property of TCP.

It might be difficult to handle for the NBSS layer though since we dont get
(and dont want to get?) information
to the SMB dissector of what is happening down in the NBSS dissector.
