OpenWRT - not sure why anyone would want to use dd-wrt?

I’ve thought about this as well, you could market it to gamers or content creators who care about latency. Nano pi r6s with openwrt and buffer bloat configured for their connection. Nicer/simpler UX on top maybe.

Firewalla did something similar but imo their UX is nice but actual product isn’t great (lots of issues on gigabit links ime, overpriced).
