If I were to do this , I would twist the end with some lineman pliers before putting the terminal on to crimp.... I'd be concerned about the end of the loop arcing back to the wire if it were just folded around like that - especially in higher voltage lines.
Correct electrical wire gauge to the correct wire terminal end is best ! Crimp with quality tools . There is Garbage Freight and Knipex quality tools in the market along with terminal ends and electrical wire .
