If your linear PSU has a decent smoothing cap say 10,000uf you can take out the one in the Caiman as it is rated at 16v. If you are worried about RF you could just use a small cap or tant rated at 25v say.

Not certain about the rating of the Gator as I don't use one (stayed with the passive mod). I think, but not sure, that the Gator takes an unregulated feed from near the input cap.

I still think that a dedecated 5v linear PSU inleau of the superreg is the way to go.
