I like the idea of cutting Fett out of Jedi completely. I'd prefer if he just shows up in Empire, does his job and then disappears. Makes him much more intriguing.
I'm certainly against MORE Fett in Jedi. Why would he be on a manhunt for Han? He has no reason for a personal grudge. At least no reason that we see in the films. Han was just a bounty Fett cashed in on.
