I would be strongly in favor of such happening.Of course it would be catastrophic to have a Monaco F1 race with the same cars for some but for me would be really beautiful seeing all the drivers with an equal car during this really slow track.The best of where this can happen is in SPA in Belgium,I would love that really fast race with the same car for the drivers.I think it would add to the beauty of a F1 calendar if we held a couple of such events and also the driver will get better recognition and in the top cars any driver would have a chance to go if they show good skills during such events.
It may look impossible for this to happen but it would be very beautiful for us F1 fans.
^ You are right. Having a new mode in F1 will also be a big refreshment for fans, organizations, and also the drivers in my opinion. Yes, there will be haters for a new mode but I think that it's worth a try. As we are not replacing the current mode, if things go south, the new mode could be shut down. But I really want that the better drivers to get rewarded for their driving skills rather than relying on their organization to make a better car.
