Attaching subkeys to a different master key

Is there a way to detach subkeys from a master key and attach them to
a different master key? I'm guessing not, but just double checking.
The problem is, I'm using APG (Android Privacy Guard) on my phone, and
it wont accept keys exported using --export-secret-subkeys. I was
hoping to generate a new "fake" master key so I don't need to put my
real master key on the phone.
