I think it's a bit messed up... it can be cool for small parts or cameos as a form of tribute, but if it becomes a thing I'll hate it...

It's similar to what happened to hologram versions of dead musicians on concerts... when they did it the first time to bring back Tupac for a couple of songs it was cool but then not long after they did a FULL concert with a hologram version of DIO singing along a live, real band and that was creepy. Hated it
