1985 23' Straight Inboard Deck/Stringer Question

[TDL]

Have a 1985 23' straight inboard seacraft that I'm thinking of changing up deck layout.

Specifically, looking to make the forward step up/storage to a flat deck, and then enlarge the battery box (see picture below with hatch) to one big in deck storage space from the back of the battery box all the way to the bow.

Does anyone have any pictures/know what the stringers/area looks like from the battery storage to the bow? From the forward storage compartment, there's an inspection hatch that faces aft. I can put my hand in/down there and seems to just be the bilge/empty space. Added picture with general cutout idea.
