...another vote here against epoxy of any kind by itself without some other additional structural support.
If you can remove the paint and rough the exterior surface for an inch or two past the hole on both sides, those CF repair kits with a CF sleeve would probably work (linked above). Otherwise, sleeving and brazing the sleeve in place with some sort of steel tubing of the proper diameter, or some thin sheet steel. You still need to clean down to bare metal to get a decent braze attachment.
At the price youi mention for the frame, and with that kick stand plate as original equipment, I'd be inclined to toss the frame unless it has some sentimental value. I have repaired stuff like that out of sentiment.
