‚ÄčI don't see why this application would demand a force field that's any
different than what you'd use for other proteins. The structures being
unavailable is a different problem rather orthogonal to force field or
simulation option choices (and obviously one you would have to solve
first). Is this something you'd want to run in a bilayer environment? In
that case, you should include that in your model somehow (and using an
explicit membrane would require you to use a set of lipid and protein force
fields that are compatible; e.g., ff14SB+lipid14 in Amber or CHARMM 36).

Good luck,
