gpgsplit can help here but you need to calculate a new subkey binding
signature.  There is no tool for this instantly available.

Now that PGP is able to very signatures made with a subkey, I
considered to merge my cert-only key with my working key but I won't
do that because it will be easier to create new subkeys for the
cert-only key and keep the old working key around for decrypting old
