Rogues in Remballo for solo play?

One of the guys from my regular group is a little behind the rest of the party as far as XP goes. I was thinking of running him through Rogues in Remballo as a solo adventure. He's a 4th level Bard, good stats, decent gear and nothing magical other than a few scrolls and potions.

I haven't looked at the adventure with an eye to solo play but wanted to throw this out there to see if anyone had any thoughts.
