The old Minolta 70-210mm f/4 is pretty good. That could be had cheap. A Tamron 70-200mm f/2.8 is excellent, though very large. Combined with a fast 30/35mm-ish lens and you'd be set.
If you wanted to reduce size you could go for an Olympus or Panasonic mirrorless and get a lens like the Panasonic 35-100mm f/2.8 for a comparable setup, only much smaller and lighter.
Choosing a smaller body keep in mind that your hand size. For those with large hands the ergonomics of something tiny like an Olympus E-M5 can make it a pain to use, especially compared to a full-sized SLR.
After hefting a larger setup like the one above for a long time switching a smaller mirrorless setup is such a relief. Those fewer pounds make a big difference after so many hours.
