The hair thing, I can do.
The con I'm planing to attend is only in June so I have plenty of time to grow out my hair. And I have had longer hair before, so it's not such a big deal. I had had a haircut not too long before those other pictures were taken, that's why it's so short.
Though I probably won't grow it out as long as it is in that particular picture. I mean Gambit's hair varies on the artist, anyway.
I'd probably grow it out at around this length (or a bit longer):
