"If we lived in the post apocalyptic world of Mad Max, with no reasonable alternative, I would suggest thorough cleaning, duct tape the hole outer surface, pour liquid steel or some such into the cavity, Let dry, remove tape, cross fingers, and go another gazillion km."
As I was reading this, I was thinking of something I did long ago to fix a hole in a transmission case on a truck. Find the largest coin that will fit in that hole if you were to round the hole out a bit so the coin has something to "grab". Tape one side of the hole, put the coin in for some structure, JB Weld, fingers crossed.
I had the luxury of being able to look under the truck repeatedly for many miles until I was satisfied that the repair would hold. If you ran without the plastic cover over the sprocket for a while, you might be able to do the same.
