25s are probably a bad idea. 28mm could be OK. I weight 220 lbs and have used 700x32 tires the 8 times that I've done the entire Katy. I have ridden short sections of it on 25s but it was rather rough.
I just bought a gravel bike with 650bx47 tires which is probably overkill for the Katy, but I'm looking forward riding it there shortly.
One thing that I would recommend is fenders. They really help if the Katy is wet or even dusty dry.
