While I certainly mean no offense to you, I feel as if you haven't properly portrayed how the RP community as a whole feels about these sort of concepts. I get a sort of "Meh you'll be fine, some might not like it though...." vibe from your post and speaking from roughly 5yrs experience in this RP community I'd insist it's so much more than that...
While yes, it's not unheard of, you'll certainly find a majority of RPers within FFXIV being entirely against this concept. A large number of them can barely tolerate the entire Shadowbringers expansion zones as being impossible to get to without being the WoL. And while you may be able to find a certain small group of RPers that will tolerate this, the vast majority will be against it.
Nobody has the freedom to tell you what you can't or can do. But with a concept like this you are really going to have to take @Lihya Zharipoh advice and find a specific crowd of people who don't mind this type of charcter. So while I do agree with what's said above, I didn't want you to be disappointed when finding the majority of the community will frown upon it. But if you are prepared for that, then go for it! Either way I hope the best for you and best of luck searching it out! XD
