Interesting idea Pedro. For regular kite surfing, the goal of the first wave kites was to basically allow you to tow into the wave with kite power, but then turn off the power so you could surf the wave, with the kite drifting along, then re-engage the kite when you kick out. But even without a foil, it's pretty rare to see kite surfers actually drifting the kite and surfing, unless it's perfect conditions with side-off wind and long waves. Most of the wave riding in the videos is powered turns, flying the kite ahead of the nose of the board.
Seems like with a foil, it's even more rare conditions that it would work, where you could just park the kite, then surf a wave with the foil without any pull from the kite. We're really only just at the start of people attempting to foil in waves with sup or paddling ... what it'll probably take is one of those surf oriented foils, by someone who knows how to surf, and a maximum drift wave kite. (and while Cloud is certainly has its advantages, I'd think any good drifting kite can achieve this)
Something that makes this less feasible: of the surfers I know, kiting or not, very few are interested whatsoever in foiling. And for those uninterested, many see foiling as an abomination. So the talent pool to take this on this challenge is quite limited.
For me, I am totally into riding swells with the foil, maybe obsessed by it, but if there's actual surfable waves I'll likely be on my surfboard.
Finally a technical note: in my limited experience, the smaller kite that is comfortable to crank upwind on the foil, is not necessarily ideal when attempting to go down the line on a swell. When underpowered, the kite won't drift and risks back stalling. The small kite crew say you have to loop it to keep it active, but to me that sounds like it would detract from the surfing experience, to have to madly look a kite while trying to ride the wave. A bigger kite that is properly powered for a surfboard, but OP for a foil, will drift nicer when going straight downwind. So, seems to me a smaller kite may not be the answer to this. Though you don't want a kite big enough to actually have any power in it while drifting the wave, just enough to fly along with you.
