6* definitely, 7* possibly but will need a few tries at least. I'd look at trying to level them all as high as you can before the event and ideally take Tarkin and Stormtrooper up a gear level if you want to be certain. If you can reallocate some mods from other toons that'd be good too, you'll need some high speeds. Bar Thrawn, R2 is the hardest Legendary to 7*
