this is not good idea, and even if you did it wouldn't help - 
if the key have multiple subkeys, and you encrypt to that key,
message is encrypted to only one of these subkeys, normaly to newest one.

some time ago I added key to another as subkey as an experiment
(with hex editor and hacked PGP6.5.8), so it is possible,
but there are several problems, most important of them is
that original key and key converted to subkey cannot coexist
in the same keyring, at least not in PGP,
some PGP versions chrashed when I tried to import both,
others didn't crashed, bot imported only one of keys.
(I didn't tried to import both keys in GPG..)
