Hmm does the Riposte that you are following work exactly as the Scout or is it different in some fashion? With that Houserule, taking Daring Outlaw is a very solid choice.
I do also like the Factotum, is there some particular aspect of the class that you wanted to utilize?

As for my avatar, its from an online webcomic called Charby the Vampirate, the character is a disguised Tony VonHarnier.
