Have you considered media blasting?  With a suitable media, you could 
remove the solder mask without damaging the laminate.

Subject
[TN] Solder mask removal






I need to remove multiple broad areas of solder mask to expose ground 
plane on populated boards as a result of a layout fubar.  Laser removal 
appears to be the least risky and doesn't require masking, corrosive 
chemicals, or deftness with an X-Acto or Dremel tool.  Does anyone have 
experience with this removal method?  Recommended or non-recommended 
suppliers?

Thanks,

Gregg
