Can FrameMarket work as a general child theme?

I see how the FrameMarket theme is a good choice to work with the e-commerce plugin. I am trying to determine if FrameMarket can also serve as a child theme for our general use. We have our own hooks and scripts and what I want is a barebones theme I can use to build out. My thinking is that it would be great if I could have one theme as a framework for both general use and e-commerce. Or is there another WPMU theme that would be better -- already "barebones"? It must have a drop-down menu built in. Some of the basic themes out there do not.
