it might work IF you can get LAS-LHR then an airport change to LGW for the LGW-DUB flight as they would have to give you your luggage to switch airports, just make sure they don't have your FF number on the LGW-MAN flight.
I've done that myself, albeit a number of years ago so things may have changed regarding the luggage.
You mix here, he wanna go MAN instead of DUB, his tix is back to DUB.
As long as BA don't know your real plans you can check to dub for the day after (if your ticket is overnight) and collect your bags in London and check in again to man but don't tell them nothing about another ticket.
