If Bilko's academy team lists are accurate then Thornley was almost always a left centre (unless the centre/winger numbers were reversed). I thought it was Marsh who played on the right alongside Charnley. It probably won't make too much difference though as he has played on the right before.

I'd keep Faz at right centre he did alright there on Friday night.

If we're going to put a Second Rower at centre, i'd rather go with Hughes and leave Farrell in the pack.
