I think you can put your Bandwidth management shaper in front of your
router and add a static route in it to forward all packets to the
router. This way, the shaper becomes the router and you will have total
control of your traffic management rules.

(1.) Shaper (Gw) --> Router (wccp) --> Squid

Then, you can use WCCP on your router for forwarding web requests to
Squid's port transparently.

Or you can forward your all NAT web traffic from your bandwidth shaper
to your Squid box. You need a static route-map in your router to run
Squid transparently.

(2.) Router(Gw/route-map) --> Shaper ---> Squid

However, these are just my thoughts. I maybe be wrong and somebody else
should have a better idea and way to deal with your case.

One thing I want to advise is: Why run NAT on an ISP level? You are
bound to face problems sooner or later!

Or simply, it's not worth it! If possible, get a minimum /22 network.
