'86 Studio Series Grimlock needs his sword.
He could also benefit from screw hole covers for his dino face.

 

I still want bulkier arms for Trypticon. Aside from that and a few mentioned above, an upgrade/replacement kit to turn Galaxy Upgrade OP's blue bits black.

 

Articulated arms for Siege Rumble and Frenzy.

 

I still want a new Evergreen styled head for Siege Barricade.

 

A battle damaged crunchy top piece that can plug into Siege Flywheels legs for when MMC TorTor is widely available.

 

Devastator upgrade kits reissues count?

 

A G1 Arcee chest for Bigfirebird Nicee.

also the cancelled G1 Arcee Head the company was going to make initially.

i know some fans are trying to make something, but having a third party like perfect effect, or DNA designs or shadow fisher would be a godsend as they would have the tools and resources to make this easier in larger batches

 

SS-38 prime feet,head,and shoulders

 

Toy accurate head for Siege Trailbreaker.

 

Gap filler for Earthrise Arcee's shoulder pontoons.

A better face for MP Sunstreaker.

A chest upgrade for MP Arcee.

Gap fillers and stickers for SS86 Jazz.

 

New heads with better face sculpts for SS Blurr and Kup and Kingdom Cyclonus.

 

This isn't really about upgrade kits, but Kingdom is giving us the ultimate versions of some characters that are better than the existing MP's.
I really hope someone oversizes Hot Rod and Blackarachnia with some diecast in appropriate places and MP-worthy paint.

 

Keep the gap filler kits coming. I freaking love those things. I’d like some for the Earthrise Seeker sides. The bot mode has some pretty egregiously hollow sides.

I’d love some piledrivers for Siege Frenzy/Rumble.

I would love some generic weapons kits. Just make a bunch of weapons that could be used among a number of older figures - old Legends class figures in particular.

 

I want some old style trailers we used to get. Give me a power master style trailer for seige/earthrise please

 

Okay kinda random, but all these years later I'd still take a kit to make Energon Devastator not look sad compared to the other upgraded Energon combiners. Some people still own that thing.

A G2 trailer for one of the Earthrise Primes, with G2 guns and maybe a swappable comic head and Roller, would be fun.

A Megastorm head and G2 toy rifle, teaming with Toyhax conversion labels, for GS G2 Megs.

 

doubt any of these would ever happen but....

new backpack/cover for mp shockwave so that clear part is a solid colour and covers and hides the whole of the gun barrel in robot mode

new facesculpts for mp sunstreaker , ironhide, ratchet and hound

 

A non-scratchy chest for Quietus from Fanstoys.

 

I'm reviving this thread.

Because SS86 blurr needs filler. And a bottom piece for the car mode. That flat plastic is so bad on such a good figure. I don't care if he can't hold the weapons there if it means he doesn't look like a flat board on the front

 

New feet for earth rise Ironhide and ratchet. I've got some 3d printed ones but I'd rather some more solid moulded ones.

Maybe something to make astro works and the other modulator in that set to make them different from the originals.

 

Need an IDW upgrade kit for Kingdom Cyclonus
