Transferring ERC-20 ICX off ledger

Like a lot of newcomers to this sub, i have heavy ICX bags from 2018 which are stored on my Ledger as the old ERC20 tokens. I'm looking at the steps invovled in converting them, and it requires extracting my private key from my ledger, which is almost a non-starter as ICX is such a small part of my portfolio. I see it's possible to swap from a ERC20 ICX from a MEWwallet. Is it possible for me to copy my ERC20 ICX from my ledger to MEWwallet, and extract that private key from there instead??
