So lore dump. Spoilered, just in case.
All these things said, I think it would be most unwise, if not completely lore-breaking to RP as an Ascian. They are immortal, nearly omnipotent beings which we know next to nothing about and are harbingers of chaos and destruction to feed their terrestrial god, Zodiark. They can be "defeated" yes, but not killed (barring one single exception).
Now, because I'm generally not a naysayer to the ways or things people wish to RP, I will say the closest thing to an Ascian that would be "lore-friendly" to roleplay, would be a character possessed by or used as a tool for an Ascian, as we have examples of this aplenty ranging from the SMN storyline, the 1.0 Limsa Lominsa storyline, and the 2.0 MSQ.
