Oh no! Not Necromancy!
One of my early mod ideas for Sins before it was released in 2008 was "Federation, and Empire". However i pulled the plug on it due to how Amarillo Design Bureau, and Task Force Games FIERCELY defend their IP. When i was modding Starfleet Command in the late 90's, and early 2000's there were several incidents of cease, and desist sent to artists. Especially when it came to Starfleet Battles specific content. Like the Andros, the Hydrans, or the Kzinti.
The massive rule sets could be "partially" implemented, but much of everything would have to be "simulated", or worked around. There is much in the rule sets you couldn't get even close to in sins. I was toying with the ideas of making ships specs "SSD" lore friendly. Like was said there are no specific shield arcs so all shield arcs would have to be combined to a single shield. Same with Hull, Armour, and Excess damage. All would have to be combined to get hull hit points.
The weapons could be better simulated. Except you will have to forget about firing arcs. Firing arcs are very basic in sins, and it seems the arcs are geared more for ships that can fire 360 degrees. We still have annoying weapons firing through the ships own hull issues. However all weapons in sins hit no matter what. Its the degree of damage dealt after buffs, and debuffs that matter.
Some SFB stuff could be simulated through abilitys like scatter packs, and wild weasles.
Regardless there still is the IP issue. I'm not a big fan of cease, and desist letters.
It's been a long time since i played F&E, and i probably forgot most of the rules. However know the idea has been toyed with
