Is this easy to do? Ubuntu Touch on Redmi 7

This is to install Ubuntu Touch on a Redmi 7 cellphone.
Is this easy to do.  I have no idea of where to begin.

Installation:

Full wipe and format data
Flash mashkoukras vendor v2.img
Flash ubports_GSI_installer_v10.zip
Flash UbCartel or GenomBuntu (has anbox support)
Flash halium-ramdisk.zip
Reboot to system!

Notes:
Anbox installation - https://del.dog/amagucu
Password is "phablet"
To connect to shell use "ssh [email protected]"

Before I buy the 2nd hand Redmi 7 I want to know if I stand any chance of success.
