Default B1 PSSR Question and idea

Dear Nelson and all others.
I have a question about the PSSR of the B1.
Will the PSSR of the positive side with the drain of the gate-follower be higher or lower than that of the CCS at the ground?
When the CCS yeilds a higher PSSR would it than not be benificial to move the Gate-follower to ground and have a CCS in the Powersupply?
This can be accomplished in two ways, both keep the CCS with an N-Channel FET, the Follower can be either N-Channel with inversed PS or with P-Channel with the normal negative ground.
Comments please.
Rick
