Let me ask, and see if I can get any info before remaking them. A good friend works as a costume assistant for Star Wars at the Disney parks, and while she might not be able to tell me anything, she might be able to tell me something. :rolleyes
I also think these are very different from the screen pair. I don't think that mesh even exists on the original pair. Most of these types of replicas for display- not the traveling exhibitions-(and I'm fairly certain this info is correct) are not made from the same materials, fabric bolts, etc. If they can't source it from the same places, the fabrics were one-offs, or if it isn't cost effective to replicate, they'll usually do the exact same thing we're doing. Studying it and reproducing it. Only, they get paid for it and have access to much better resources. That info also comes from a Disney employee friend, so take it with a grain of salt because I can't verify the process.
I will ask her tonight and report back.
