coating with epoxy

I've been building a little dinghy for some time and sadly no matter how slow I try to go it seems to be getting closer and closer to my having to finish it.

This is a stitch and glue design with marine ply. It is designed to be encapsulated with epoxy then painted except for the bright-work trim.

The plans and west system directions call for several coats of epoxy.

The problem I'm having is that you are not supposed to thin epoxy but it always seems so rough.
I put it on with a west system roller and tip it out to get it as smooth as possible but by the time I sand it so it is smooth it seems as if I sanded most of it off.
I'm thinking I will just do three or four coats without sanding to build up some depth before sanding. Since I'm doing this an hour or so at at time I can't time these west system coats to wait for it to get tacky before the blush.
So I'm thinking of switching over to system 3 epoxy which does not blush and just do a pot every night until I get three or four coats then sand it smooth which will take off the last coat for sure.

Does this sound like a plausible plan?
I have to switch to system 3 epoxy anyway as it is required as a base for the system 3 LPU paint I'm planning on using.

I'm planning on using the system 3 LPU paint which is a two part water based paint which I'm told will not smell too bad because I'm working in the basement and don't want to stink up the house.
