There is not a single program on the planet that can read or write *.max files, except for 3ds max, Autodesk VIZ and (to a certain extent) VIZ Render.
Polytrans and others need max installed to be able to use it in their conversions.
A few of the basic features can be read by tools like Deep Exploration, but not the real format.
The 3ds max file format is not a straightforward format. It is more like a script and very, very dependent on the version of 3ds max/VIZ, the installed plugins etc...
(replace n with any version number of max bigger then 1)
max (<= n-1) can't read max n files
max n can't write max (<= n-1) files
So I don't ever expect ArchiCAD to be able to write them.
What could possibly work is writing an ArchiCAD Exporter that writes a format that is more suitable then *.3ds or *.obj or *.wrl and then a MAX Importer that can read it back.
So basically, yes it would be convenient, but it won't happen, ever.
