I have confirmed the process that has been outlined for myself. I have successfully generated offline a new EOS keypair, and then using my nano ledger through MEW was able to associate my NEW EOS public key with my original Ledger Nano MEW Address containing my ERC-20 EOS tokens following the instructions given by EOS42 et al.

Now, the idea is, within the next 24 hours, my EOS public key account will be frozen as I understand it. This is really great news! This effectively means we have solved the problem. All we have to do now is await further communication and instruction from ECAF, to regain liquid control over our EOS.
