M.Thomas for Chubb?

Should I do this?
.5 PPR and the rest of my team is as follows:
QB - Prescott
WR - Hopkins, Ridley, Hardman
RB - Gordon, A. Jones, Murray, Mostert, J.Hill, M.Davis
TE - Z Ertz

The Hopkins/Thomas duo is very hard to give up but I’d like to buff my RB core while waiting to see if Melvin is going to come back.
