Ideas for increasing KTM Duke charging system capacity?

Hi guys. I've got a 2010 Duke 690 (usa spec) and I've put on heated grips, and taps and a controller for heated clothing too. I want to ride in comfort even when it's cold. Here's the thing... the Duke's charging system is rated at 224 watts. I'm worried that my electric gear is going to over load it.

When you look at the specs of a KTM with a 990, like the SM-T, it has a charging system with 450 watts. Kinda like my BMWs or my Gold Wing. Big output with plenty of room for accessories. Today I was at a friends house and we put an inductive amp meter around the ground strap to the battery. Not sure what unit of measurement we were actually looking at because the meter was set up for AC, but at idle, the number was 1.1 so it was reading something. When revving the engine, the number went up to about 8. When revving with the heated grips on, it went to 5. When revving with the heated grips and the heated vest plugged in and cranked up to high, it stuck at 1.2 even at higher RPM. With heated grips and the high beam headlight on, it stuck at 1.2 also. Not a whole lot of headroom I guess. It never went below 1.

What can I do to upgrade the charging system? Does anyone make a stator with more output? Would a stator with a higher rating from another KTM plug in in place of the Duke's? If I can't go that route, I'm thinking I can spare some wattage at least by replacing the headlight with a lower wattage HID kit??

Any thoughts and suggestions appreciated.
