These ones ?

I personally installed the oxford's Hotgrips on both a GSE500 and my VFR750m and I've been very happy with them.

I would be cautious with just fitting a heating resistance under the original grips.
1- would the grip fit back with the added thickness ?
2- would the original grips survive the heat ? (my oxford hotgrip can be really hot on max setting)
