Considering the hydroplane:

The hydroplane lands and takes off on smooth water via a flotation device called "paid of pontoons" which are essentially a pair of boat hulls. The hydrofoil significantly reduced drag to a boat in the water hence its popularity. Could this hydrofoil tech be applied to a hydroplane's pair of pontoons? How would such an addition change landings and flight efficiency?

Concerning helicopters:

Helicopters are notoriously lightweight and some have a pair of pontoons as well as their hydroplane counterparts. Could a hydrofoil under a helicopter improve long distance voyages over water by keeping the helicopter just above the surface of the water the whole way as the hydrofoil negates gravity? Could a hydraulic jet engine be added to the helicopter's layout to make use of not just air friction but also water friction which is vastly more fuel efficient?

of course I'm sure there are patents in the works about these very topics, but hey...since when has that stopped DIY?

hydrofoils are a fucking meme! The transport cost is similar to that of an airplane. That's right, it takes roughly the same amount of energy to go some distance with a hydrofoil as it does with an airplane. Except you'll probably get there faster with an airplane

First one might be possible second one is a no.
The point of hydroplanes is that at speed you get all the benefits of being in the water (stability and something for your engine to push against) without the need to push a bunch of water out of your way as you move.

Planes and especially helicopters don't get the same advantages because they don't push against the water to move forward.

You can use ground effect over water. The problem is that you need relatively calm seas because you're only a few feet above the surface.
