I actually just made a blind char. Perhaps we can RPÂ sometime and they can lament their 'disability' together. 
But I did something similar. Only instead of elemental forces helping and guiding her (even indirectly) she senses the aether in living things or things with high concentrations of aether in them. Like materia and such things. She still uses a cane to move around for those pesky barrel/crates/doors/walls/etc that might be left in a pathway.
As for lore viability... don't see why not, for the whole elemental aspect. But I'm not an expert on lore of the elementals. Just know what I've seen other pull off in the game.
For instance I know a char (not blind) who did have a friend wind spirit. Used the garuda egi to represent the spirit. And he still ended up with plenty of RP for having such a 'rare gift'. Not all might accept it but it -could- be done if it's something you'd like and it doesn't sound like you're the type to overpower it.
