I have a sneaking suspicion that if that time comes to pass you will make very clear to loved ones or anyone else who may be inviting you to weddings that they ain't getting a cake plate if your invite says Mrs Droleshubby.
When the person expresses a preference, that ALWAYS trumps the "rules" of etiquette. I think it's more or less always been that way. But if you don't know the person that well, the rules are there to fall back on.
