If you wanted to keep your name, there are plenty of beautiful blue shiny pokemon! For example, I'm a fan of Cloyster, Starmie, Gardevoir/Gallade, Bisharp and Tyrantrum! I think CaptainBlue is a pretty cool name with one of these mascots :D
In ORAS, I believe the only way to get a shiny Pawniard would be to breed one. With the shiny charm, MM isn't that bad I bet. I don't think MM is terrible without it, so I'm sure with the charm it would be much better!
