Excuse me if I consider that line of thought as being completely silly!
By having two Squadrons....instead of one.....does the then generate an excuse for a Wing and yet another bunch of staff pukes and add yet another layer of bureacracy and cozy billets?
If the Aussies can pull it off with a single Squadron....why cannot the RAF....the most professional Air Force extant?
Divide the Crews into Flights under one Squadron Command and leave the aircraft as a separate resource with the Techies.
That is how the US Army runs its Helicopter Units...with anywhere from 16-24 Aircraft per Company (Squadron).
Pilots are assigned to Platoons, Enlisted Aircrew are assigned to a Flight Platoon, the Aircraft and maintenance staff are a separate "platoon".....all under a single Company Commander who has an admin staff to include Operations staff.
