Well you could never really expect a Pariah to get into a Space Marine Chapter, the revulsion is too strong. Those Marines that were possessed would not be able to serve him. Just being arounf him would drain the Daemons of power, and probably banish them. Since he can't recieve any of the Chaos Gods' gifts he can not show himself to be favored, so his Warband would probably turn to a Champion that had been granted power. Actually they probably would have tried to slaughter him when they turn to Chaos.
