Brendan, it won't happen. Only way would be a super-secret society of authentication that no one would benefit from except the 'authenticators' themselves.
The big TPA's have a strangle-hold on ALL autograph authentication, and it benefits all the big players (AH's, consignors, etc) financially to such an extent that nothing is going to change.
I avoided TPA's for twenty years, but recently dealt with both PSA and JSA and was very impressed with the expertise of each. Given the authenticated Ruth's we've seen, it's easy to see that this is about money - not expertise.
