Can I get the first letter in my Plus+ username changed to uppercase?

My Plus+ username is xanadeath (anyone looking here feel free to add me :p). I used to sign up for everything with the first letter being lowercase, but now I like it to be uppercase. I wanted to know if it would be possible to have my name changed to Xanadeath (capital X) without losing any account data. I searches GS for related topics, but all I found was someone who's question was never answered.... it doesn't seem many people have had this sort of problem....

Thanks
