Honor Harrington?
Man, thats going to be difficult to try and do, even an unofficial setting (Is the Saganami Island Tactical Simulator the official game for HH, or is it an official game?)
Never mind. Off the top of my head, beam weapons are either going to be restricted to range-3 weapons or represented by carronades (going by SX here, haven't really gotten into SAE yet, especially with all the minor problems). Missiles (pre-pods and that system in AAC) are going to have to be either drones (customised for either detonation laser missiles, nukes, ECM missiles or simple decoys) or some really customisable weapon mounts with the same options and ammunition constraints.
And another thing: Starmada has always seemed to me to be good at handling the 'space opera' SF setting really well, but HH isn't 'space opera' as regards space combat. Ships never see each other in space at combat ranges, and even ships in the same task force have a difficult job seeing each other. You'd have to have a seriously large map to even attempt to fight a purely HH battle, methinks...
