That's a good approach to have.
I might not be the best person to describe current MPs, as I was a bit out of it lately, but I'll try.
This run of PMD wasn't super big to begin with (it's a rerun, and playing as pokemon doesn't seem that popular), but lately, it seems to be carried by a single anon. I believe if you started interacting with his character, he'd be eager to respond, and according to the Great Anon Theory, if we have a couple of effortfags it can lead others to be more active too, so there is a chance.
For City, I think it had a good start, with people being interested in the new path, but then it got a bit stuck, with people being gun-shy. In particular, there seems to be the main group of sinners on the bus, but most of the anons aren't sure what to write in this setting, and how to engage without breaking up the group. I believe that getting through those initial hurdles will be tough, but afterwards it could get easier. Again, a couple Great Anons are required to pave the way.
MHA is an eternal moloch, with a long history, a couple bibles worth of effortfagging, and hordes of Great Anons, who seem unfortunately to have perished. It might come back from the dead, as it has done so in the past, but there is also a chance that we've lost the Great Anons in the hack, or they just lost the spark.
Finally, there is an option of starting a new MP, but finding a good cyoa for it isn't easy at this point because we have some specific requirements, but if we had something to meet the criteria and a couple Great Anons to get it started, I think it's not the worst time.
I could try to expand on those points, but I'm not in the current runs of PMD and City, so for that, other anons might be a better source.
