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.

Thanks,

My player made it about 1/3 of the way through Four Corners before being captured. He did escape, with a little deus ex machina, and is determined to try to finish the adventure up.

Lesson learned is that rogue assassin's have a solid chance in solo play due to stealth, sneak attack and the assassinate ability.
