Yes you can key both out e.g. with primatte.
Then you can combine both with a "Matte Control". Make sure to set it to "Combine Alpha" and "Minimum".
Also you don't want to postmultiply twice so do not multiply the keys or pipe the new Alpha into a separate Matte Control, with the original plate as Background. Set it to "Combine Alpha" "Copy".
Then you can post multiply before merging over a background etc.
