It would be nice! ...but no. Only Good Order units may transfer weapons during the MPh, and there is no way to transfer/recover weapons during the AFPh (except a SMC immediately recovering from an eliminated unit).
Also, only a SMC can ever recover SWs from a broken unit (as per A4.44):
Only a SMC can Recover a SW/Gun possessed by a friendly broken unit, and does this by rolling a Recovery Final dr of < 6 (Δ) in its RPh/MPh without need of MF expenditure;
Finally, it could be that the broken unit possesses more than its IPC in SW. In this case, it could drop the excess DC in order to rout, but this wouldn't happen until the RPh.
