Challenges and troubles:
Your character would be very, very difficult to relate to. The roleplaying community skews from the highest highs of power levels to the lowest lows, and your character would be experiencing panic and anxiety literally spanning across multiple worlds. There's enough trouble brewing in Eorzea, and your character is not only living through that but ALSO experiencing the most important and historic adventures across the annals of the universe? That would make it extremely hard to commiserate with you: Your trouble isn't something 99.9% of the community can help with. Roleplay is a lot of give and take, and I think that a plight of that level, i.e. having visions of worlds and worlds of strife, would render almost everyone you meet as a completely helpless "Dude, that sucks" degree of powerlessness.
Your character could very easily be construed as completely insane. The number of people who know for a fact world-traversing is a possible thing is a very, very small number of both the canon game world and the extended roleplay community. Even in a world of magic and godlike dragons, claiming that you're seeing other worlds and meeting people who don't exist would probably get you arrested and/or thrown into some sort of asylum. You'd look and sound like a crazy person.
It would be very easy for your "template" to overshadow your character's identity. "That's Jim. Jim sometimes falls through dimensions and meets extremely important canonical characters." It's a drum I tend to beat when looking at adding "templates" to a character ("template" here meaning "extra doodad or character perk used for flavor." Things like aether-sickness, iconic jobs, vampirism/hearer/werewolf or whatever. Things that don't define your character, but are just extra traits or ideas you've attached, usually for plot points.)
Subjective opinion: Roleplay is about give, take and collaboration. It's definitely a lore-acknowledged angle to see between worlds. The issue is that something of that magnitude doesn't let a lot of people interact with your plot. You'd get people interested, probably, but how do you get them involved beyond being sympathetic and listening to exposition?
Keep in mind my default mindset to looking at plans angles and concepts is to riddle them full of holes before seeing if they float. Don't let anything I say here persuade you to give up your idea. It'd make for a unique set of experiences, but I particularly don't see an easy way to get others involved aside from being an audience to your woes.
