@Young:
Instead of “rewriting” or “reorganizing” the Europe and Pacific books into one, I have thought hard about the possible creation of a separate book that would only be reference, index, glossary or an epic “Table of Contents” if you will. The Star Wars Rebellion game has something like this and it’s extremely effective, plus this would be a complete original work which would not alter the copyrighted material, but rather add a whole separate document booklet that compliments the original material.
Yes, that sounds like a good practical solution to the problem, and very useful too.
