If this is true the i am clearly doing the wrong thing.  The CA hierarchy should 
run top-bottom, not the other way around.

IMA MOK was introduced mainly because .system keyring was static at the time.  
Assuming i have my root certificate in .system how can i add more keys to this 
keyring?  The new keys have been signed by my root CA?  Is this possible since 
your October patch-set or i've been missing something this whole time?
