The 7204 is a good choice.

We used to use this setup a lot to receive customer circuits using 7206
routers. A VXR will work fine with 4 or more DS3s coming into it
(28 x 4 = 112 customer DS1's). If you are only doing one DS3 then a
non VXR will work.

We also used T1 muxes, but for the opposite purpose for what you are
considering it for. We used them if the telco would only provide
individual T1s, to mux them up into T3s to go into the 7206, to
avoid putting low density port adaptors in the 7206. CAC makes one,
called Widebank. It's easy to use, with minimal configuration, or
perhaps none, you plug in the T1s and the T3 and it works.
