I think once you have laminated the curve, the curved door can be made out of access door cutout opening.
I found it would work in my build curved front. The cutouts are quite stable. Having two access doors to the toilet from outside and inside make total sense. If you look at the video link I sent you above, that guy did exactly that. The outside access door is more of a smaller hatch to load camping gear than a door, that makes sense too.
I have 3mm baltic birch inside and 6oz FG outside of 40mm XPS foam in build there. I would use a thinner plywood if that was economical and available in my area. I think 3mm baltic birch plywood is plenty good.

I bought a pile of 900x1200x30mm (2'x3'x1 1/4") xps sheets, ripped a whole lot of 1 1/4" square lengths of wood and basically made a ladder of wood with xps sheets in the gaps between the rungs. Glued it all together and let it dry.
Then kerfed it, put it out in the rain for an hour and bent the whole thing around the bow section.
I plan to sheet both sides with 3-4mm ply. Seems very strong and also fast.
I like the idea of foam construction but like the tidyness and simplicity of hard wooden corners.
Will try this for the whole outside and inside positions as well.
it might even work.
I like what you did with kerfing, did you use some jig to make them as good as they look in the photo? I agree with you on simplicity of having hard wooden corners. One challenge I had was working time of glue when laminating large sheets of plywood to sandwich. Maybe if I soaked some water on the plywood that would help, otherwise I found that epoxy worked best for me there. Next time I'll try to put some water on the plywood especially in curved areas.
How are you going to clamp the curved and flat panels for the glueup? I am interested in that very much.
