We are also facing a similar problem as we move accross to Revit. Revit conceptual tools have improved quite a bit in the last release or two, but there is a new package that could be worth investigating too - Vasari. It is an Autodesk product, currently in the labs: (http://labs.autodesk.com/utilities/vasari/).
It is being touted as Revit light, with a large focus on conceptual development workflow and energy analysis, and it is fully compatable with full Revit as you would expect.
Have a look at some of the videos such as this one:
It certainly looks interesting, maybe not the answer you are looking for, but it may have a place in your office, even if it isn't with you!
My limited (so far) experience in Revit to Max shows linking to be an ok option, but you need to fiddle with the units as Revit is (internally) set to use feet and scaling of materials can't be over ridden with UVW maps. You may have to Reset Xform first.
I'll be keeping an eye on this thread to see if any other alternatives come to light....
