Well, it's "only" a standard action, yes, but beyond battlefield positioning or changing weapons/shields, a move action doesn't allow you to do much to affect the battle... no damage, no spells, no item activation. So, readying an action still, equivalently, takes up an entire round of combat contribution hoping for something to happen, and if it doesn't, you've lost out on a turn contributing meaningfully to the combat. So, it seems to me a readied action isn't a good thing to base one of the few (comparatively) special abilities you get from a 10-level PrC on.
I see you've changed it into Thespian's Luck and Thespian's Reposite (which I believe you meant to be riposte :P), but I still think a readied action isn't a good deal. Instead, I'd make it tactical and more of a flow with the rest of the class by making it an immediate action by spending a Flair usage for the day, but make it melee attacks only, since parrying an arrow or crossbow bolt seems a bit too outlandish even for supernatural luck (IMHO), unless the Dashing Swordsman takes Deflect Arrows... though there's an argument to allow the parrying of thrown weapons. Since, as an immediate action, it would only be able to be done once a turn, you can remove the cumulative penalty, and just leave it as a simple -2 to the attack.
