I am trying to change my root partition from BTRFS to EXT4, but I am
looking for ways to do it without a full reinstall of the OS.

Reboot to a liveCD or something.
cp -r the  BTRFS filesystem to an EXT4 filesystem in a partition,
preferably of the same size.
Save the label and UUID of the BTRFS filesystem.
Edit ...ext4/etc/fstab so that / will have the correct filesystem type.
   I think this is the only place needed.
   Anyone know for sure?
Copy the new partition to take the place of the old one.
Restore the label and UUID that were saved.
Reboot
