One of the things we had to be very clear about when 
we passed the 802.1ad PAR was that there would be no 
new interface parameters to the ISS and no new major 
entities/processes within the MAC Relay Entity. I 
believe that means that this "two FCSes" suggestion 
falls under the heading of new work and should be 
considered as such. As noted by others it could have 
very significant effects on bridge implementation 
architectures, and obsoleting bridge architecture is 
well outside the intent and discussion of the PAR.

Separately it has been noted that use of MACsec to 
provide integrity (without necessarily requiring 
confidentiality) would  provide significantly greater 
guarantee of no changes having been made to the frame.
