If the tied rewards are tweaked or removed, why not, I honestly think it could be useful to practice your own part of the fight at least. But much of the difficulty of the content comes from having to coordinate 8 people, the fights are designed and balanced around that, not 1 person and 7 bots.
I'd rather see new hard content for solo or light party specifically designed and balanced for that amount of players, than changes or options to currently existing content, though.
