How could a name like "J_A_B" possibly detract from your immersion when names like "IamK00LD00Dz" or "yomomma" or even "187686451" are already common? I know you probably weren't refering to my name specifically--but the idea is we already have names which aren't much related to WW2 air combat.
Immersion aside, in reality I would never use a phony handle. I use my own name. My in-game handle is my initials, and the space marks are necessary to disginuish that fact. "J A B" with spaces but no underlines is acceptable to me (although I don't particularily like it), but I already tried that and can't use it. My current in-game name is stupid and I hate it enough to not wish keeping AH.
If you're looking for immersion, the proper route is that of EverQuest--require everybody to have a "proper" name. AFAIK, AH has not taken that route yet.
I am still hoping HTC responds as to whether it would be possible to work something out. If they don't respond by Friday, I will stop punting this thread--no need to spam the BB.
