I honestly wish you luck with all your many petitions, but realistically I agree with Nic and don't think they will work.
WB were doing great with collector releases up until the Golden Collections ended five years ago and it's been downhill since then. They've flooded the market with numerous double-dip collections and it seems that now WB cannot see any value in continually restoring old cartoons. It also seems that there are now people within WB who think certain cartoons should be locked up forever. This attitude is not going to result in the kind of releases collectors want to see and is even preventing BluRays that seemed ready to go (e.g Tom and Jerry Vol 2) from seeing a release. Reading between the lines, it seems that even trying to get WB to release a complete Tex Avery collection (a release for which there is world-wide demand) is an uphill struggle.
