I hate to be a naysayer, but I was part of a team which tried to do exactly that in the Homeworld 2 engine, and we got shut down due to IP considerations. It seems we were given a cease-and-desist (we eventually got some correspondance with Mr. Weber himself, though it didn't avail us) in favour of this: http://www.rulethehonorverse.com/ .
While I would dearly love to see my favourite military sci-fi universe in Sins, it would be even worse for some people to try and then get shut down like we did. 
All that said however, I can actually think of a few ways to get the characterstic combat elements. We already have broadside combat in the Akkan BC, missiles could simply be spawned fighters with little ability to turn, shot down by anti-figher "Counter-Missiles"...
Alas, if only...
