Thought of a couple more:

A comic accurate leader class Jhiaxus, something beefy and imposing.
G1 Reissue Blue sided Bluestreak  .

 

Pretty much anything Beast Machines, or at least anything that requires a new mold. The designs are generally not very toy friendly (assuming you want screen accuracy), the line was not popular, there were only 26 episodes which didn't really run after the line ended, and most of the Beast fans are far more enamored of the Beast Wars lines.

 

I have three.
G1 Toy accurate Jazz (I want wings and rocket)
Jetfire thats a nice blend of Valkyrie and G1 (something along the lines of his classics design but bigger)
And Slapdash.
Ill never get my slapdash or if they make it. It will be a dumb exclusive which means I won't get it etherway.

 

Lewin Resources Optimus is exactly this.

 

Sadly...my "they're never gonna make this toy" is almost exactly my "list of transformers I'd like them top make updates for"...

Skyscorchers
Accelerators
Rotor Force
Laser Rods
Predators
Turbomasters
Cyberjets
Stormtroopers
Color Changers
Lightformers
MW / RID2000 Flipchangers
Spychangers / Gobots
Throttlebots
Landcross
Micromaster six-combiners
Omnibots
Triggerbots / Cons
Firecons

 

any form of Godzilla crossover due to the licensing of the toys in japan belonging to Bandai.
needlenose
new versions of bayverse skids and mudflap
new accurate tfp toys
new combiners with the scramble city compatibility

 

Hi Ishmael!

 

Marvel Spanner and (a more accurate) Scrounge.

 

Holy Hannah!

 

It is worth noting that the Lewin OP is meant to scale with 6 inch figures, so some Joes might feel too small.

Theres the Mega Action Series OP and Megs, which are official but non-transformable representations which work well with Joes.

 

Hmph. I totally missed these. Looks like I'm gonna have to start saving my pennies.

 

I’m sure a kidney would get you all three.  

 

A Leader sized Armada Megatron who's compatible with a mostly in scale masterpiece release of Energon Megatron who can wield him like in the cartoon.

 

The little Unicrons are far more dangerous than the fully grown Unicrons are. They are small, agile, quick, hangry AF (no, that wasn't a typo), and have just started out on their quest to devour the cosmos. The Autobots would have never defeated a tiny Unicron.

 

How about actual sharp Tetrajets and not the half assed attempts they gave us for Siege.



Also these two, I dare you Hasbro.


also I second this red guy from @Prime Noble

 

I mean, I don't really need both. Right?

 

Marvel Crosscut and Ferak

Of course giant purple griffin the fortress as well.

 

A 100% faithful modern update to G1 pretender Roadblock... First for me was Doubledealer, and now I got my perfect version of that, so my next hyper-niche fixation is this decepticon Ultra Pretender

there’s so many play features to this, he’d make such a good commander class. I’d hunt down the g1 version if I knew it wouldn’t crumble to dust. I really hope the rumored pretenders in legacy eventually lead to a Roadblock update

 

We need more Quintesson variations!

 

Faithful updates for all the later Pretenders would be sweet
