FWSM and CSM - Naming the control-plane PortChannel

Hopefully a very easy one for someone to answer - given that the internal backplane (FWSM <-> Cat65xx) and (CSM-S <-> Cat65xx) is automatically generated, and seemingly can't be changed (i.e. our CSM-S works on Po262, or 261 and I think the FWSM is something like Po276), will IOS allow me to name the PortChannel and/or automatic interfaces?

For instance, would the following be permitted/work, or because these are automatically generated, could it break something?

On the FWSM (Firewall Services Module), I get the idea of using "svc-vlans" etc to chose your "Virtual Line Cards", but for the CSM-S (Content Switching Module with SSL), there doesn't seem to be any "svc" or other configuration for the backplane transports at all on the Cat65xx; it's just "there".

CSM-S

Cat6500#conf t
int po262
 desc *** CSM-S Control Plane PortChannel ***
int range gi6/1-4
 desc *** CSM-S Control Plane Trunks ***
end

 

FWSM

Cat6500#conf t
int po276
 desc *** FWSM Control Plane PortChannel ***
int range gi7/1-4
 desc *** FWSM Control Plane Trunks ***
end
