Removing it (temp) to rebuild everything from the ground up may unironically end up breathing life back into the series.
A neopets Pokemon game would be something on the side though, akin to Let's Go. They would use it to test the waters the same way said game did for overworld encounters.
Just about any concept can be good if the developers put in enough creativity/passion into the project. However, at its core, Pokemon is still a classical monster collecting JRPG, so the idea of battling/leveling being removed isn't happening. Like stated above, this only happens when there's major revamps to said system.
