Yes it is possible. The first thing is that you must not distribute
the keys while they are in this revoked state: do not send them to
anyone, and absolutely do not send them to a keyserver.
Here's how to unrevoke. It's a very manual process. Be safe: make a
backup before you do stuff like this.
1) Export the public key into a file.
gpg --export (thekey) > mykey.gpg
2) Split it into parts:
gpgsplit mykey.gpg
This breaks the key into multiple files with names like
"000001-006.public_key".
3) Figure out which packet is the revocation. It's likely to be
"000002-002.sig", but make sure with:
gpg --list-packets 000002-002.sig
That will show information about the packet. If the sigclass is
set to 0x20, that's the revocation. Delete that file.
4) Put the key back together again:
cat 0000* > myfixedkey.gpg
5) Remove the old key:
gpg --expert --delete-key (thekey)
You need --expert here so GPG will let you delete the public key
when a private key is still around.
6) Import the new key:
gpg --import myfixedkey.gpg
