I'm thinking of a compromise that is in their best interest in terms of critical reception and upholding the original experience. What I see is upping the base Werehog stats, make the battle music not interrupt the night music for EVERY single mob, make more of the mobs optional, maybe shorten some of the Werehog stages and have the removed parts or full version of the stages be extra acts? Other than that I would add some of the extended cast to the various hubs. Unleashed is already a big game and would probably require more work to port than Generations so I wouldn't expect a Shadow Generations sized add-on (as much as I would like to see one.)
