I think you'll find the salary cap has never applied to Wigan so don't think that was ever an issue with regards to Hock's potential return.
Any settlement of Gleeson's contract will count under the cap, if they have room left ... they have room left. I imagine Leeds have a fair bit despite any noises that may come out of Headingley from time to time to the contrary.
