user30017: Can i compose a multisig address where one of the signatories is a multisig address?
In order to create a multisig address we need the pubkey of the signatories.
bitcoin­cli addmultisigaddress 2 
'["pubkey1", "pubkey2",..."pubkey(n)"]'

Is anything stopping me from using a multisig address as one of the signatories?
Essentially: can one of the signatories be a multisig address (one that currently starts with a 3).

user24925: No this is not supported behavior. You can manually add the public keys from one multisig script into another, but a multisignature script can not be nested within another.
