How to fit 5s Lipo in E-Revo

Hi all

I plan to buy an E-Revo and fit single b/less motor system. I have a 5s lipo 6000mah I want to use and wondered if anyone had ideas how to mount it. The obvious solution is running it across the chassis where the rear motor would have been and speedo up front where 1 of the steering servos was placed (I will be converting to 1 steering servo).
Anyone done something similar? If so any pics would be great.

Other option is to convert nitro revo but that seems a little pointless!
