chosing Inos - consequences at early stages of game

Im currently clvl 42 doing all quests just like suggested here and not liberating cities. But i have been using exclusively FB and IL and i would really like some stronger spells as on hard diff frost fire wave and ice explosion dont really cut it for me so:

Can i get the 5 artefacts and chose inos to get meteor and fire rain and come back to doing quests and start liberate the cities? Or will it mess the game up like lead to some fights between factions? I have not been to vanguard yet but i have the teleport rune and 3 adanos artefacts.

Cheers!

Don't think I've tried doing it in that order. Can always just save, hand in the artifacts, and then quick travel some city in Myrtana.

yeap - I will save the game and make a tour of all cities to see whats going on. but atm I am backtracking all old chests to get staff of invulnerability
