Heated grip elements under stock grips?

Just picked up a new renegade 1000 and love the grips but would like them heated. I have the 5 setting symtec box to use and was wondering if I can put heating elements under them and how hard would it be?
I saw a video online of a guy doing it on a motorcycle and of course he makes it look super easy.
Also would the elements work with with the 5 level symtec heating box?
It’s really not because I’m cheap but because the heated grips I’ve seen really suck as far as grips go. They really lack grip.
