Since your existing box is in the wall, you are probably going to have to cut into the wall anyway just to get the 50a wire from the main breaker to the sub-panel, unless you can somehow use the existing wire for the old hot tub. It might not be that much more difficult to go head and make a cutout for the sub panel and have it flush like the main panel as long as you don’t put it too far away. I am not an electrician but I am pretty sure that you can use conduit to surface mount both the 50 amp line as well as the 220 and 110 circuits that you add around your shop regardless of whether the sub-panel is flush or surface mounted, which would be a lot easier than cutting holes in the wall board and drilling holes in the studs. I think that most code also requires that you put steel plates behind the wall board on studs where you run the wire if it is not encased in conduit behind the wall.
