So would you consider doing a project like you suggested with permission from the original Appendix creators? Your familiarity with MultiAVCHD is a good start.
If someone does this I still have all of the original files on around 10 DVDS for Alien Redux Workprint (Appendix 2) in DV format. This would be a better source to author a Bluray as the DVD was authored at a lower bit rate to fit.
