I think it's actually possible, as long as Meat brings his Rocktelz show to the West End, and Jimmy makes some serious headway with the Bat musical.
I spoke to Jim recently (publicly on his facebook page) and he said he was "feverishly" writing on the book for Bat.
He's also mentioned shortly prior to that that they were getting into the casting stage.
If both Meat and Jim were both based in the west end at the same time, I see no reason why it couldn't happen.
