I don't see why changing your CPID, is such a big deal... Just think of it as your handle, hell in other games I use several names, but the account is the same. It really sometimes is fun to fly under a different name, just because its different.
With an old ID, people expect or don't expect from you, with a new one they really don't know what to expect, and for the most part they'll think you suck, and you can Annihilate them!
But... a nice idea would be using your perks as a commander in a mission, and purchasing the Perked planes, used for a mission... thus those who have the perks spend them, (commander doesn't lose any) but since the commander has some squadies that don't, they can fly them with his permission using the commanders perks.
Or on another twisted note... the "Commander" idea can be used for instance he wanted to purchase drone bombers to compliment his already planned mission. The commander of a mission would lay in a course, and target for the bombers. Then depending on type, number, and experience level of his bombers, which means experience of crew as well i.e. gunners/bombadier, he can spend his perkies for a succesfull mission (of course he'll get a perkie bonus calculated on mission objectives etc..)
