I think it'd be alright. Cuter on a child, yeah - a little bit serious on an adult, maybe.
Reminds me too much of
Orson Welles, and is too surnamy, for me to really like it.
I agree with you, that "awr" is not how we say the Or in
Orson.
If I say awr-son, with aw as in bought, it sounds like arson.
I say it the same as I say the Or in
Orlando (which BtN has marked as "or").
I say the Aur in
Aurelia or
Aurora as awr, like aw in sawn or bought.
