I don't think this is probably the right direction to venture out in...

I have a counter proposal, instead, use -frepo to select where you  
want to lay down the debug information.

To that end, let me show you half of the code...  I''ll leave it as a  
project exercise to up port it and finish off the other half.

When last I built this, it removed just about 100% of the debug  
information for a large C++ header file. (Carbon.h).  As for what  
needs doing, you would need to modify collect2 to choose one  
instantiation point for each unique type.  I'm hoping that you could  
do that with 50 lines of code or so.  From there, just additional  
testing and finishing off the rough corners.
