Porsche could do a lightweight 2+2 version of a midengine R8 type coupe, or they could also just create a entirely new successor to the 911 that doesn't have to be a homage to a previous model.

Yes they sell every 911, they also sold every 365 and Super 90, soon will be the Taycan taking money. In this new Porsche era of $100,000.00 4cyl Boxsters, maybe another new sportscar from them is too much to ask for.
