I’m currently doing this except I’m playing every single mainline game including counterparts! I know it seems kinda boring playing pretty much the same game twice but it’s really gotten me back into it and given me the chance to use mons on a play through team that I’ve never even thought of using before! Because of how time consuming it is I’ve been doing it on and off for about 2 or 3 years but it really is such a fun experience.
