It would be crazy expensive to do an all electric Wrangler with any kind of range right now. Manufacturers have to get to scale to bring that cost per kWh down. Since the Wrangler is so inefficient, it would take a HUGE very expensive battery to go all electric at this point. I suspect this is one of the reasons why GM brought the Hummer back to be their electric super truck. That way, it's a stand alone model that doesn't have to compete agains a cheaper gas version of itself. If the average consumer walked on the lot and saw a $100,000+ Wrangler sitting next to a $65,000 gas model, that's going to be a tough sell.
