I don't think a drum is very practical there.
With an efficient roaster and good agitation it's possible to roast a finished lb with a nice profile and 1400watts. the fan and drum motor don't use much power. Adding an afterburner puts power consumption over the top.
So what I need is one of these:and one of these:Agitation plus heat and look out - I am in the coffee business!

Voila, instant half bag coffee roaster!
I didn't care for the toasted lint and dirty sock after taste
