I'm considering using the ZyXEL eircom P-660HW-T1 as more than just a router. Maybe I can run Pihole there instead of a Raspberry Pi, and use the antenna to extend coverage.
I haven't heard of anyone setting up PiHole directly on a router, but it's definitely feasible and not overly complicated. You can often just adjust a configuration option in the menu, or you might need to update custom firmware. Either method should let you get it running within about an hour.
I’m not sure about the exact difficulty, but creating custom firmware can be quite challenging and isn’t always feasible depending on your skills and resources.
It seems you're wondering about finding DD-WRT support for your router. There are likely resources online that can help, though it might not be straightforward since you're not familiar with development.
