Has anyone tried to MEB or EB an ssd from any larger retailers with success? Or what about swapping SSDs and returning them?

You can try Western Digital direct.

I know from a friend that FTID works on them for certain, although it did take them a little over a month with frequent contact (once every 1-2 weeks) from the opening of the return to them finally being refunded.

Do you think I can MEB them?

No idea, sadly... You can always attempt it and if it fails then you can FTID them.
