Ghost Rider & its devil's bike

Ok, a lot of people told me "there's no way Lego gonna make a new piece for a lego idea set". Ok... what are the alternatives?

Flames plugged in the back of the minifig?

...or the piece used on inferno? (Legot Set 70162) 

Many people told me that this last proposal was the solution... but I don't think this piece is really nice for the Ghost Rider...

It would need, at least, to be in graduation colors, from clear to orange, not to cover the skull color on the face.

Ok... it's a Lego Ideas Project... but it's also a Marvel product... which is a Lego wonderful license...

So, let's imagine Lego producing just one little specific piece... just one ;)

I tried to remedy the weaknesses of my minifigure and designed specific skull and torso to fit the original character.

Next step : design the flames to plug at rear of the head ;)

Thanks to commenters advices, I added an enemy to my Ghost Rider : The Super Villain Jack O'Lantern

Some history :

Jack O'Lantern was created by Mark Gruenwald and Rik Levins and first appeared in Captain America #396, although he is visually based on the Jack O'Lantern who was created by Tom DeFalco and Steve Ditko and first appeared in Machine Man #19.

Steven Levins was a mercenary who fought Captain America and Spider-Man as Jack O'Lantern.

This incarnation of Jack O'Lantern was a member of the loosely-knit band of Red Skull minions called the Skeleton Crew. He was also a partner of Blackwing prior to joining the Skull's group.

He also worked as an enforcer of the gangster The Golem and in this capacity, fought the villain The Hood when he interfered in Golem's machinations.

Levins resurfaced just before the Stamford incident. He was hired by the terrorist organization R.A.I.D., and, along with JackHammer and Shockwave , was ordered to flood the Thames Tunnel, but their plans were foiled by Union Jack's intervention. All the villains were arrested and Jack O'Lantern was most likely deported back to U.S.A. and then recruited into the Thunderbolts hero-hunting squad.

While pursuing Spider-Man through the Manhattan sewers alongside the Jester, Jack O'Lantern was shot through the head and killed by the Punisher. However, he reappeared later possessed by a fragment of Lucifer's soul, and exhibited the ability to detach, levitate, and explode his head, among other powers. However, the Ghost Rider was able to exorcise him by ripping his heart from his chest, setting it aflame, and putting it back in his chest causing it to explode inside.

Powers

Demonic Transformation: Steve Levins can transform to Jack O'Lantern any time at night or if he's really angry.
Superhuman Strength: As the Jack O'Lantern, Steve Levins is superhumanly strong and capable of lifting about 5 tons.
Superhuman Stamina: The mystical energy that empowers Jack O'Lantern prevents his muscles from producing fatigue toxins during physical activities, granting him limitless superhuman stamina.
Superhuman Durability: Jack O'Lantern's body is highly resistant to physical injury. He is capable of withstanding great impact forces, temperature and pressure extremes, powerful energy blasts, high caliber bullets, and falls from great heights without sustaining injury.
Fire Manipulation: Jack O'Lantern possesses the ability to generate and project fire at will.
Penance Scream: Once eye contacted with somebody if Jack O'Lantern screams the person he is looking at chokes to death.

Weaknesses

Too much light and being in a church.

Jack O'Lantern is is shown flying on The goblin glider or on a kind of Flying broomstick. 
It is this last option that I have chosen, so it can be used as a means of locomotion, or as a weapon.
