Theoretically possible. The downloaded application should contain gdb
stubs and start running them, then gdb should be able to connect to
the target, and continue or run the application without using a load
command.

Of course there may be a few problems when it comes to the little
details, e.g. how does gdb know that the code is already present on
the target side? Does it check, or can you just issue e.g. a
jump instruction at the gdb prompt?

I suggest asking on the appropriate gdb mailing list, see
http://sources.redhat.com/gdb/ for details. Searching that mailing
list for phrases like "connect" might also give some useful hints.
