I just noticed on delta.dumb that you can buy a bundle consisting of priority boarding and a wifi pass (for a domestic DL flight). It's listed under the place where there's information about the mileage boost option to buy RDMs in association with a flight. This *might* be a way to buy wifi and use the DL AmEx credit. The priority boarding is probably the same zone as a nonelite with a DL AmEx card would get, probably called zone 1 but in reality it's about the third or fourth group to board.
If someone tries this, please report back.
