Although PiHole doesn't need a huge amount of power, it does need seem to need more resources than the average router has, unfortunately - it has components written in PHP, at least if you want the web frontend, and runs some SQlite DBs which might not work well unless your router has some "real" storage attached to it. It's also a pain to get working unless you give it its own local IP address. While it might work, it would be kind of defeating the point of it being "plug and play". If you have any kind of local server running "proper" Linux (not necessarily a pi) it's pretty easy to run pihole on it though - there's a docker image or you can fire up your favourite other Debian-based VM/container image and install using a shell script.
