Well if you think about a 2-Disc set, here's my suggestion:

Disc 1: The Film (which should feature the classic New Line Cinema logo)

-English 2.0 Original Mono

-Blu-Ray Audio Commentary with Sam Raimi, Rob Tapert, and Bruce Campbell (or maybe all 3 commentaries combined)

-Reconstructed Full Screen Theatrical Trailer (using Disc 2 of the R1 UE. Featuring the classic New Line logo, and the Knowby narration at the beginning)

-Reconstructed US TV Spots (Again, using Disc 2 of the R1 UE)

-Book Of The Dead Trailer (Semi-Reconstructed)

Disc 2: Within The Woods/Bonus Material

-Within The Woods

-UK TV Spot (can be found on Youtube)

-Japanese TV Spot (Again, found on Youtube)

-Compilation of the edits/censored bits from the BBFC certified 1990 Palace Pictures UK VHS release

-1983 Vintage Interview with Sam and Rob (possibly found on Youtube, but it could've been deleted)

-PM Magazine Detroit TV Spot on Renaissance Pictures

-1982 Tom Sullivan TV interview

-The Uncut Version of the Incredibly Strange Film Show

-Siskel and Ebert Review on The Evil Dead

If you're trying to find the classic New Line logo in full screen, the original individual single disc of A Nightmare On Elm Street has it. If you need any ideas for future Evil Dead Treasures Collection DVDs, don't hesitate to ask. ;)
