GC has a pretty active benchmark forum. It might be a good idea to check in with some of the people on there.
Holograph has compiled an archive of datasheets by state here: http://www.holoscenes.com/special/geocac/ds_archive.html
Not really sure how to integrate it though.
In my opinion, it's not really worth it to add them to our site. The biggest complaint on GC is that the list is outdated. That means constant updates to the database. If you are looking for an easy way to see them on a map, use: http://benchmarks.scaredycatfilms.com/
. But that's just my opinion.
