You might have some success using the UVTools Beta by Whaat (Dale Martens). You can find it here
It creates a proxy obj bridge between SU and mapping software. I tend to use it with Ultimate Unwrap, because that's specifically concerned with mapping, so pretty light on its feet; but Dale claims that the process is also compatible with Max. It enables you to go pretty much instantly between SU and the mapping software, creating something as close as we're ever likely to get in the way of a mapping studio within SU itself.
I've been using it to develop a range of fully mapped figures. They're modelled in SU (for low-polyness), mapped in UU3D, then any small, subsequent tweaks are applied using the UVTools plugin.
