You're working with the USGS historic topo map collection. In the long run it might be helpful to communicate to the appropriate office of USGS your need for these to be provided directly in GeoTiff rather than in GeoPDF. I'm sure that our people discussed the format issue and came to their current decision based on many factors, including the demand they foresaw for specific formats. But if there is a much larger demand for GeoTiff than they had anticipated, I imagine that might enable them to revisit the decision. Of course the conversion would entail a cost, but if the number of realistic users is large enough, it would seem efficient to do this conversion once for everyone rather than separately by each user. The key issue, I suspect, is balancing the number of people who would benefit against the cost of creating and maintaining an accessible archive of converted GeoPDFs. But the information needed by the current maintainers is the extent of the demand. This is just my opinion, and I'm in no position to promise anything, but I do encourage you to communicate your needs to the current maintainers.
