welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.
There's no way to unrevoke your key. Make sure to keep it in GPG Keychain as you can use it to decrypt messages encrypted with it's public key part.
I would suggest to craete a new key with the email addresses you are looking to use. And make sure the old revoked key is also in revoked state on the key servers if the key resides there.
This KB-article explains how to add more than one email address to an existing key. The email addresses in a key are called userIDs and you can add as many as you want. You can of course also create an additional key for the other email address.
Important note: Note that all email addresses you add to a single key can be connected to one identity. Depending on your use-case this might be wanted or should be avoided. Please consider that first and then proceed.
The steps if you need to remove and add a user ID later would be to revoke just the single user ID you do not want to use any longer and add new user IDs as needed. You can then select which user ID to make your primary by right clicking on any user ID in the user IDs tab and then selecting "Primary".
