The C7200 as you mention would do shaping for you.
Shaping, BGP, and NAT on a NPE-G1 with 200Mbps traffic in my experience
is pushing the performace of the box a little more that I would be
comfortable with.  Havent played with the G2 so far.

You can also have a look at dedicated DPI boxes.
Cisco does the SCE (previously pcube), and there are many others:
packeteer, allot, sandvine
These may be nice as they are L2 bridges that don't require drastic
topology changes.
However I believe it works our more expensive that a c7200

With those features enabled (bgp,qos,nat) you'll reach the CPU limit
before you reach any policer limits.
