Let’s see, what would get me to happily buy that box?
Hound (Earth mode)
Jazz (Ricochet or G2/Actionmaster. SS or Buzzworthy mold since both good)
Wheeljack (Cybertron Downshift scheme)
Sunstreaker (Don’t really know since the current one is kinda trash. Even better color matching would be kinda ehh. Maybe an interesting G2 scheme? Masquerade Breakdown?)
Trailbreaker (Riggorus scheme)
I've been thinking along these lines but trying to manage expectations as well by figuring there'll be a theme for the set. My guess is it'll be these characters rather than new-character redecos in a unified deco theme; could be all-animation deco (like the other 86 movie releases in Buzzworthy) or toy deco (like the Beast Wars releases in Buzzworthy). If we have to go down that road, my wish is for a hybrid where it's toy based decos with opaque plastic.
But if they do this as, say, a Legacy themed crossover battle set?
Earth mode Hound is a lock since he's why this set exists.
Jazz: RICOCHET. From the SS86 mold. Full stop. I may also accept a Kick-Off, but I've been waiting for a Ricochet from this mold forever.
Wheeljack: I'm really taken with the idea of a toy deco WJ, especially since I associate his other related color schemes (Cybertron Downshift, Alternators) with an entirely different altmode and body shape. (Of those, though, I'd like the Alternators one.) So idk here. A G1 Downshift would make a bit of sense, but would be kind of bland since it's basically unpainted Wheeljack.
[instead of Wheeljack I wish they'd use the Kingdom/G1 Sideswipe mold. We haven't gotten that outside that 2-pack release and a redeco as Clampdown. G2 Sideswipe out of that, yes please. Manages to update the mold and give another shot at the deco, which was in another exclusive multipack.]
Sunstreaker: I'm open to the possibility of better color matching with opaque plastic, but if redecos as other characters are available, then give me Alternators Dead End. Unlike Alternators WJ, this is less altmode-tied and more color scheme driven to me, idk.
I did also see a nice custom SG Goldbug using this body in mostly black with yellow piping. It would be a nice G2 Sunstreaker look, especially standing beside G2 Sideswipe, who also goes mostly black with his old main color as accent. Might even use it AS SG Goldbug pending a head swap.
Trailbreaker as Riggorus is a solid choice as I still want them to finish out the Diaclone etc colors for these molds. That would just leave Reboost and one or two others, no?
