Pared down for the sake of space but as to the bolded, I really hope so. But I've wanted literally anyone up from the minors in place of Hernandez and Arroyo for literally months, and Valdez is probably the easiest move, so my answer is certainly yes.
FWIW, I'd move option 4 up to option 1 and I'm hoping that Bloom is actively trying to do this right now. All Duvall does right now is take at bats away from a superior player that has more term and a bigger part of the core (Duran, Yoshida, Verdugo, Refsnyder). There are enough articles out there that it at least seems Duvall has some value on the market, so get whatever you can for him and give the time to better players.
I'd also move option 1 down to option 4. Though my preference would be to go get an actual upgrade on the middle infield, but that probably isn't in the cards.
A name I'd be really interested in from the trade market (if they sell) is Brandon Drury from the Angels. Bloom was in on him in the off-season, and to my recollection, Drury might have taken less money to go to LAA, but with that team coming apart at the seams, it seems like he'd at least not be totally against the idea of coming to Boston (obviously if he for some reason hates Boston, then don't pursue this) but I think it was just a scenario where he liked something about LAA more, not that he wasn't interested in Boston at all.
He might be something akin to a "Schwarber lite" deal in that he's presently on the IL, but expected to be back soon, so he could be off the radar a little bit. I have no idea on if LAA would be interested in something like this, but the idea of Mata and Hamilton for Drury checks out almost exactly in terms of value on BTV, which - for all it's warts - at least makes me think it's not outlandish. As a RHH that is capable of playing lots of positions, in many ways he would be an upgrade on Duval (just as an OF, not that he can play CF) and he would serve as Turner insurance, freeing up a move of Dalbec if he can get anything of any interest in trade (not sure he can, but since it was brought up Dalbec was "Turner insurance", Drury would be a much better insurance policy). He'd also be a really good "gap" player with term for next season as well as the Sox see whom of Yorke, Meidroth or Valdez ends up being the 2b for the 2024-2030 core.
