If Klentak could replace Franco at a reasonable cost he would, other than that, it's a matter of opportunity.
Makes no sense to trade Galvis unless you get a decent prospect, i.e. top 20 or better, a marginal prospect, better just to keep him for a year and let him walk.
Hernandez will have value, just a matter of waiting for the right deal.
Building up the back of the bullpen, adding an innings eater, adding veteran depth for the bench.
That's all I really expect, the farm system is deep, despite criticism they did land 4 of the top 50 LA guys plus the Braves catcher, they should have a great draft.
They have money and will add some players, but I think the best use would be to front load a Nola extension.
