I would avoid basing it off con - it is already too important a stat for characters in any system in which hit points are related to con (in my games, con does not affect hit die rolls, but only starting HP, so it'd work there... but in RAW D&D, it's probably a bad idea to base further bennies upon a high con).
I'd base the ability off dex instead of charisma for what you want it to reflect - out of turn reactions to enemy attacks to reflect dodges and toughness, etc. Dexterity works because it suggests quick reflexes and co-ordination, which is necessary for warriors... and it's a stat most melee types will have a decent rating in. Not to mention that it helps rogues be a bit more slippery, which I think is a good thing for them.
That, or you could go the 4e route and basically say "pick the highest of these three stats; base your ability off that stat". Which is an idea I'm actually a pretty big fan of.
For what it's worth, if I were gonna do this, I'd stipulate they can only be spent outside of your turn, like interrupts or something, so that the player has an incentive to pay more attention outside of his turn. And it helps reflect your "reacting" bit, above.
