Artie,
Sorry to say but I think that will be how it's going to be for quite a while.
Senior FO's have moved off the 744 to the 777 or are holding their place looking for when the new hardware comes onto the bid system. The 737 no-one knows what's happenning to! There are alot of LGW line creeping into the summer LHR rosters for the airbus though!
The 777 is going very senior with internal transfers, the A380 is anyones guess but could also go very senior as could the 787 which will leave new joiners with the Airbus or the 744 (which can't be too bad can it!).
Good luck.
(As an aside the current BASSA storm in a teacup is having no effect whatsoever on current or forward bookings. The summer looks to be very, very busy!)
