Very cool. Its actually a very stable driving buggy. I did one of these about a year and a half ago. I didnt go white as high power as you are planning though. I've not seen another one converted so I'm looking forward to seeing your results.
Here is a link to a vid I made of the first time I ran it and the build thread I did.
