Need help converting to Brushless

[2FastSS4U]

I've got a Savage X SS that i'm building and have decided to go brushless my main problem is that the only conversion kit i've seen to do this is at www.kershawdesigns.com and I thought that it was a bad design due to 1.) The motor should be mounted inside the TVP's for protection and 2.) the battery trays were too high and wold possibly get damaged easily in a roll over, plus they are plastic. I've been searching for a while now and have not been able to find any products at all to help me in my conversion. If anyone can help me it would be so awesome. Thanks for your time.
