Barbara who?
Only joking, I know what you mean. It's hypothetical anyway because I don't think we'll see Barbara play professional RL again. You raise a few interesting points though.
Coote to SO. Yes, I can definitely see that working, very clever player and would mitigate his lack of pace although we'd lose a bit with defensive work.
Lomax to SH. I can see that too, at this stage of his career I think he has the brains to move us around the pitch, would need to improve his short kicking game though.
Fages to HK. Absolutely. Tough little bugger, good hands and a good burst of pace. Also very useful if a back gets injured and has a kicking game. Smith/Eaves to spell him.
Of course none of that may happen but it gives us options certainly.
