IIRC, the master index files just list the normal index files in each 
package.  The reguler .idx files have a listing of the types wrapped in 
each module and what they are called.  This needed for SWIG's Python and 
Java generators because they need to know for every type in a given 
interface whether it is wrapped and if so where and with what name. 
However, the .idx files do not contain any information about the actual 
symbol names, just type names.  I have no idea how easy it would be to 
add tracking of wrapped symbols into these files but that may be the 
place to do it if you try.

We dealt with the dependency problems in ITK's wrappers by just manually 
coding the package loading scripts to do things in the right order. 
Since ITK has a hierarchical organization of dependencies (Common, 
BasicFilters, ...) this order just follows that hierarchy.  If you're 
having problems ordering the wrapper loading then there may be a problem 
with ITK code breaking the hierarchical dependencies which is a separte 
issue.
