No. Very bad idea and you know it.
Reapers take more than two months of full, all day long sun to thrive. If you can sort of just maintain it and not let it grow too fast, snipping off all flowers until spring, then carefully acclimate it to sun over a week or two and plant it outside, you could have a nice, fruitful bush. They're not for the impatient if conditions aren't ideal.
I made reaper sauce once. It wasn't bad. Wasn't stellar either.
That’s most likely what I’ll do with it…try some sauce. I am tempted to bite into it though…for science. It’s been stupidly hot and dry here this summer.., so best chance is this year. Good looking fruit so far, all green still. We’ll see what September brings.
