If you do allow for the feat to meet pre-requisites, then I'd suggest buffing the existing ones from +2 to +5. This also makes the feats better reflect their names. I mean, I don't expect someone who is said to have lightning reflexes to have just slightly better reflexes.
I was thinking the same thing about it being better to increase the bonus of the single-save feats. +5 seems a bit too high to me though, I'd say +3 or possibly +4 would be more balanced.
