ANH's probably my most interested film to see figures come about, so I thought about this a bit... CHEWIE's list is pretty close to mine I think, but I'd go with this:
-Tarkin Resculpt (most needed non-army builder resculpt to me personally)
-Fleet Trooper SA Resculpt (this guy finally needs the works already... If they were to include an extra piece with a scanner gun, I'd dig that)
-Bom Vimdin (my most wanted Cantina character right now)
-Dr. Evazan Resculpt (Ponda's not articulated, but holding up IMO, but Dr. E sucks, and has never held up)
-Ultimate Tatooine Luke Skywalker (easily, to me, the most needed hero from ANH is a "final" Luke figure that could easily get a STormtrooper belt slapped on him for a DSE version)
-Black Tunic Imperial Officer (again, a long-needed figure to me).
That'd be my 6-figure choice...
An 8-figure choice, I'd add:
-Ponda Baba Resculpt (He's holding up, but not fantastic, and who wouldn't love a new one? I like the idea of alternate "flipper" hands as well)
-Death "Squad" Star Commander (I'd like a new sculpt honestly, or at least a little retooling to the legs so they're a little less akward looking, and more normal height)
And honorable mentions would definitely go to:
-Generic X/Y-Winger... Young headsculpt, 70's hair, clean helmet with powder blue emblem and black visor.
-Red Leader
-Red Leader's R5 Unit
-Yavin IV Hangar Technician/Mechanic
-Luke Stormtrooper
-Han Stormtrooper
-Ultimate "Old Ben" Kenobi (is that what we'll get from the Evo one? I hope so!)
-Wioslea
-Orange Mos Eisley R5
-Cantina Midget (You know you want the Cantina midget)
-Tonnika Sisters (I agree, they're not my top want, but I'd dig getting them)
-Garrouf Lafoe (Cantina Snitch)
-Drunk Jawa Squatters (outside Cantina)
-Various Imperial Head Variants for the black tuniced Officer... Lots of them had lines, I'd dig getting some of them with the brown leather holster, rank, and headsculpt variations.
-Y-Winger ("Stay On Target", Gold 2?)
-Red 10 X-Winger (Red helmet)
-"Space"Trooper Stormtrooper
-Yerka Migg
-Cantina Dude/Spacer
-Danz Borin
-Rebel Officer (Honor Guard w/cap, though I'd like the guys with the neck scarfs to be honest)
-Yavin IV Communications Officer (Made the calls to the pilots from the base, similar, but different from the regular Yavin IV Mechanics/Techs)
And probably about a dozen other figures...
A New Hope, to me anyway, is easily one of the more fertile grounds for figures, especially army builders, even in obscurity. Lots of Aliens, droid repaints, resculpt possibilities, army builders... Just a very rich film to yet tap for characters IMO.
