The cost to ship one speaker to Danny plus his newly designed crossovers will be roughly the same amount you paid for your Crite crossovers ($300 - $500) which have cheap parts and won't improve the sound.
I'm thinking about calling UPS Freight or FedEx freight just to check and see. I was thinking the freight would be every dime of $400 and I can't imagine how it wouldn't be $300.
As far as Crites crossovers, you say they are cheap parts and won't improve the sound, but a lot of people out there speak very highly of the difference they make in these Heritage line of speakers. The parts are good quality parts, Danny even said the parts are fine. Danny may cross it over differently or whatever, but saying it'll make no difference in the sound is quite unreasonable.
These are $1,000 speakers at top prices. I think they're worth $1,000 because the wood and all is in great shape, almost perfect, and they're 40 years old. However, most people are paying $800-900 for a pair. I've got $800 in these and if I ship them to Danny, I've got, hopefully, $350 in shipping and Danny has to make something too. That's asking a heck of a lot.
