Earlier quoted context omitted.
I don’t think it would be possible in anything like a reasonable amount of time. Non-Tesla fast chargers have huge gaps for a cross-country run. You’d have to spend days waiting for 6kW commercial chargers or 240V RV plugs charging you at 25-35MPH.
DC fast chargers aren't as common but charge the Bolt at supercharger-like speeds if you have the option
Edit: just to show what I'm talking about, here's what plugshare.com shows for CCS chargers in the middle of the US:

That gap in the Nebraska is 336 miles long. Utah to Colorado is likely to be quite challenging with the mountains. East of St. Louis is another tough area.
I think you could do the trip entirely on DC chargers if you took some of the legs really slow to extend range.
