Sounds like playing with fire to me :-).

Ext4 won't detect bitrot (silent corruption of your drive's data).
You'll probably wake one day with a fsck that won't be able to recover
some files, or worst, a completely dead drive.

Your backups would also contain corrupted data (garbage in, garbage
out!).
