Good points...A lot could definitely happen, but right now I would guess that Shaw & Travis will be at the corners with Hanley doing the bulk of the DHing in 2017. One scout called Sam Travis the "next Paul Goldschmidt" earlier this year, and while that seems to be a bit of a stretch, he's definitely in the mix for next year.
I don't see Ortiz changing his mind & I definitely don't see Sandoval being in the picture, but anything could happen I guess. If Sandoval proves to be healthy next spring, they'll move him & eat the majority of the deal in my opinion.
The only way I see someone like Bautista being an option is if they move Sam Travis in a package for a TOTR starter.
