Default Stock Rom Slot hypothetical failure

Hi guys,

I'm debating if I should flash Hyperdrive RLS 14 on my stock slot in safestrap. Would I still flash the modules (I have mk2 )? Also, what would I flash in odin just in case if I encounter some problem? Would I flash the no wipe image or the full wipe image of the stock mk2?

Anndddd! last question... can you restore a backup of a rom slot 1 onto the stock slot?
