Answering the original question - unlikely the Macan is big enough and handles well enough. I'm sure Porsche will work their same magical driving experience to the Cayenne but don't need the extra space.

the Gravity distinguishes itself with its striking handling balance, grip, and precise communication. It’s a strange world we live in when a nearly 6,100-pound SUV rotates reliably off throttle then transitions into controlled oversteer with more ease than some supercars
For perspective, Porsche’s smaller and 600-pound-lighter Macan Turbo Electric is quicker on the figure eight by 0.6 second. And so is the utterly unrewarding Mercedes-AMG EQE SUV, at 24.1 seconds. But despite its higher limits, even the Macan lacks the Gravity’s superb edge-of-grip balance.
Has Lucid moved the needle with the Gravity? Is it a breakthrough SUV? In some ways, yes. Few vehicles—and probably no electric SUVs—are as dynamically sound or rewarding to drive hard. And its packaging is a godsend for domestic users, with a seat design that stands out in a segment where use of space is among the most important attributes.
How is it any different for Porsche when they still after countless of issues keep going back to Germany for solutions? I would say the contrary, since Porsche had the experience with the Taycan, the level of issues and how they handled it on the Macan is not only bad for a premium brand, but worse than average brands. This is specifically referred to how they handled customer care and the shed incompetence from dealers across the globe.I visit the Taycan forum, there are many on there that would say there have been major failures on battery technology. I totally agree with your other points. A recent owners reliability survey put MG as the least reliable manufacturer with the greatest number of defects - admittedly that includes their ICE cars. I do wonder how owners with warranty issues on Chinese cars will fare with the myriad of different dealers and service teams.
I say this as I stupidly bought a new Lexus RZ 450e in 2023 - the dealership had no experience with EV’s and everything had to keep going back to Japan for resolution. I suspect the Chinese car dealers will have the same issues. Porsche have great experience of fault resolution on EV’s due to the Taycan !
