I wouldn't recommend trying to grab a back kick, unless the kicker is terrible. You'd be much more likely to either eat the kick, or break your fingers, hand, or wrist. Grabbing something coming directly at you at a very high rate of speed is dangerous. If you have a high rate of success grabbing someone's back kick like this, I submit that that person doesn't know how to properly execute back kick.
If you're thinking of parrying or side-stepping and going for the grab, I'd say the same thing. If my opponent is able to grab my back kick, I've done something wrong.
