I'm not sure about an HID conversion, but unless it's a true reflector HID conversion, not simply a bulb swap + inverter, then I wouldn't bother. For one, since an SUV sits much higher than a sedan, you will drive them nuts when you are behind them and blind them.
Maybe look at getting the LX570's headlight unit and swapping them. May require some custom fab work, not too sure.
If you insist of getting a simple projector setup, look at
HID Xenon Conversion Kits - Xetronic Digital.
These are some of the best on the market and are digital. Just note that you loose high-beam functionality.
These
HID Xenon Conversion Kits - Xetronic are not digital, but you can add a Xenon hi/low mod.
Personally, don't do it. It really isn't worth it other than for looks at the sacrifice of annoying the hell out of other vehicles.
