Should Pinkie be a princess?

Ok, here's my reason:
Cadence became an alicorn because she spreads love, Pinkie, on the other hand, spreads laughter.Cadence became the Princess of Love, and she has a crystal heart cutie mark.I think that represents love and the Crystal Heart of the Crystal Empire.(Duh!)Pinkie's cutie mark is 3 balloons which more or less represents party or fun.In the Smile Song, she says that she likes to cheer ponies up.So......Anypony?
