easy dual boot installation of Kali on Nexus devices

Hi,

So i thought that there is this great tool for installing Ubuntu on android devices so that people could get at fast and easily on their devices without data wipe etc...
a guide for this tool is at: http://lifehacker.com/how-to-dual-bo...ice-1577325241 - How to Dual Boot Ubuntu on Your Android Device

so why not to modify this tool so it would install Kali nethunter and by doing so making the distribution way more accessible to everyone.
What do you think?
