That's a much more exciting fight in my opinion, and it's a much better fight for Chuck. Shogun's wrestling will be neutralized, and his straightforward standing style plays into Chuck's game in a way Jardine's doesn't.
One of the big factors in Shogun/Forrest was Shogun's surprising inability to pass Forrest's guard. He spent all his energy trying and failed. Everyone remembers the great Rampage knockout, but Shogun's ground game has played a big part in a lot of his wins, and if he couldn't dominate the ground with Forrest, I just don't see it happening with Chuck.
Still, it should be a really fun fight to watch.
