I wouldn't. I'd be irritated. Because, IMO, Moff Gideon is being played by a stellar actor, but if you're gonna establish a new villain you need to spend some time with him. Like Rebels does with Thrawn. We get an idea of how Thrawn operates and his motivations (remember some line about how he didn't care about glory, only what benefited his Emperor).
Right now I know Gideon is a sadistic *&&^$, intelligent and ruthless, and that's about it. He seems to have a vision, but unclear for what. Also Gideon hiring Boba is too much Vader hiring Boba = rehash

Re the base - reminded me of a castle/moat. If u send all your troops out, then u run the risk of having them ambushed in that terrain, trying to get back over a narrow bridge. Which would remove your guard from the main facility. So u cut your losses and sacrifice some of your haul.
