Oh yeah, do the whole port! This is an impressive project in every way, so go big!
If it were me, I'd build them out of styrene rod. Evergreen has a great selection of shapes and diameters, and it's waayyy easier than using wood glue and clamps. Since it's mostly an open latice-type structure, I would avoid resin. It'd be brittle, and you'd spend too much time cleaning up flash on each part with the risk of breakage.
Either way you go, I'm sure it will look great!
