reverse modul upgrade

Hi,
i like savage truck,
but reverse modul it's like s...t. not durable and more heavy.
if you want reverse and ESC brake i have a idea, you can try it.
you can lock 2 speed gear, look like my picture.


hope you know my word.

Looks like a good idea. I was thinking of locking the one way bearing on my 3 speed with JB Weld. Would this hold up? Or would a roll pin run through the whole hub be better?
