Without drilling holes might be tough. The only two things that come to mind would be to figure a way to make the hardware in a fashion that slides or clamps on to each end or to the handles for one, or to manufacture a "ring" that would fit the Go anywhere in the same way the Kettle ring works. Both options would seem to me to be a lot more work than drilling a few holes.
I used to have a small grill similar to the go anywhere, I drilled the wholes and attached the hardware with bolts and wingnuts, made it real easy assembly and removal, worked great for campouts and such. In my case, the way I had it you could not close the lid when using the roto, but i managed to cook some pretty good stuff anyway.

Let us all know what mod you come up with, might be useful to some others.
