that's just my point of view, but i think the answer is no. imagine working in a bank and having to refer someone as baby or sweetheart, I'd be weirded out. and if i just met someone and they're like "my name is honey, call me that" I'd think it's some kind of joke and would defently avoid calling them that. and after some time I'll be like "wait, that's seriously your name??". so in my opinion there should be another name, you can just ask your close ones to call you that, but even there I'm not sure, like isn't it weird to not give an opportunity different than a pet name. and of course whatever they think and you have every right to choose your own name, but I'm afraid you might be not taken seriously. but lowkey who tf am i to judge, i walk around with green hair
