The answer for the cable modem part, is no.

No, you cannot. And even if you could, you won't beat an off-the-shelf cable modem on power efficiency.

 

You can make your own router and firewall using a variety of systems (like OPNSense), but you can't recreate the DOCSIS cable modem part.

Not anymore. Hasn't been a thing since Docsis 2.0.
