I've been playing around with commercial hangars. At the moment I have a system that is identical to the military hangar in terms of cost, capacity and crew but is 50% larger and has 1 HTK instead of 4. Using this system and the commercial magazine I attempted to replicate the capability of the US Kennedy class carrier show below. While the commercial ship is larger and slower and will probably explode if you sneeze on it, it replicates the major KPIs of the Kennedy (Hangar Size, Magazine Size, Fuel Capacity), costs 400 BP less, requires no maintenance and can be built far more easily (48,000 ton commercial yard vs 24,000 naval yard).
So everything else being equal, the civilian hangar is probably too useful :)
There needs to be some penalty and I think it will have to be a lack of maintenance. Even in this case, the commercial hangar would provide a 'dry dock' capability for repairing ships in forward areas, be able to transport smaller commercial ships and act as a ferry for military ships (probably to save fuel). Also you could add a few maintenance modules and create a commercial FAC carrier that does provide maintenance for the FACs in the hangar.
