This is my idea for kitbashing Abaddon into a character relevant to my warband

[Azathothoccoult]

https://bombshellminis.com/36021-helmet-set-r10/

Essentially, get rid of the head of abaddon, replace with something else, slap either a 10mm (R10) or 12mm (R12) (which will fit on Abaddon's shoulders best?) dome helmet filled with some 'ard stuff and warpy color to simulate liquid affects inside, along with a sadistic daemoniac visage within the hazy depths. Replace the sword with perhaps the arm of a greater daemon like a Keeper of Secrets, and I'll probably keep the gun/talon just because this thing is already fantastic sounding.

 I'm just asking, since abaddon himself isn't made a giant compared to DG/primaris that I'm aware of, just wanna know that these bits will fit on the main body of the model.

Now for the lore of the chosen/possessed/abaddon stand-ins should you choose to read it


Cygnus Breachers

The Cygnus Breachers take part in ground battles but are used as the void-warfare troops trained in boarding operations by other specialists to accomadate their daemoniac bunes. With strange warped power they kick themselves out of the air locks of their ships, launching themselves into the void accompanied by unnatural symphonies and banshee wails that can be heard in the emptiness of space, echoing through the minds of those who behold their horror from portholes which should have never been gazed through. With bizarre spectral power they phase straight into the hulls of enemy ships, in squads or as sabotaging operatives launched into the interior of their enemy's ships. Their bodies have never been recovered, for the substance composing their form is tainted by the warp, and simply weeps from their broken bodies as eerie glowing miasma leaving behind a damaged empty suit of broken power armor and the cracked dome helmet which is the peculiar badge of their order.


The dome helmet is a strange addition to their wargear, offering no material protection to the head but seeming to redirect head-shots with an aura of unluckiness as munitions seem to curve around them to avoid ever touching the abomination within the armor. Its suspected that the helmet is symbolic to the black emptiness of the void of space. They're the veteran horrors of the Apparitions imbued with such potent daemonic enhancements pertaining to their craft that they have developed abilities similar to those of Warp Talons, though these phasing abilities only seem to work in the void of space a short distance from the Trapezoidal Door.


Not to be confused with normal Warp Talons in any means these veterans can be seen in a myriad of squads and using wargear ranging from the simple to the elaborate to the utterly cursed. Occasionally one will overflow with corruption beyond the containment of a normal body and develop strange limbs similar to that of daemons, or even an inhuman head leering with eldritch hatred from within the black depths of the dome.

If you can pull it off, that sounds really cool.
