The vision of Revan on Korriban was how the Exile remembered Revan from his past - as Dark Lord of the Sith. If the canonical ending is used, Revan turned back to the LS before leaving the known galaxy to fight the True Sith. So I don't think he'd attack the exile unless provoked.
And I would think the Exile has a newfound respect for Revan after learning of his quest to fight the True Sith from Kreia, so she'd have no reason to attack either (unless provoked).
This could all be changed though if the game allows you to choose whether Revan and the Exile are DS or LS based on K1 and K2.
