Give all Strike and Maritime a/c to RN.
Give all support helos and tactical lift to the Army.
Give Refuellers and Strategic transport to Virgin.
Let's face it we are almost there already:
All decent strike a/c will operate from CVF and be guaranteed a pretty invulnerable airfield near the scene of action.
All Support helos are already with the Army
Maritime a/c are intuitively with the RN as are SAR.
