If Emerica stuck to a handful of models, I'd recommend the lineup to be something like this. Bin/halt almost every other model/variant they have. Then, keep simple colors and stop making stupid piss beer colorways. More tonal/seasonal color packs. Fewer models with more focus on productive riders and specific retros done right. All easier said than done, I know.
REGULAR LINE-UP:Laced (with the padded collar)
Figgy G6
Spanky Hi G6 (or no G6 if they can't do G6 in that one)
Wino G6 Slip (Vulc & Cup)
Dickson
Omen Hi or Winkowski (can't have both imo - maybe swap either of these with one below depending on how the launch of Winkowski goes)
SPECIAL/LIMITED RELEASE:Provost G6
Pillar
Tilt G6 Vulc
Hoban (maybe swap this for one of the regular models above depending on how the launch goes)
Skater (Leo)
KSL G6
OG-1
Heretic
Experimental models/collabs, etc.
Honorable mention for regular line up: KSL G6 if they weren't planning on dropping it completely

Such a great shoe like Reynolds G6, but shame it didn't catch on with people...
