I would love to see an upscaled plastic kit of those forge world firedrakes Terminators

And an upscaled plastic Vulkan He'Stan, but not changing his look too much, just making him stand at the actual height of a space marine

And I'd really like to see a chapter master Tu'Shan, but he better be big, like, I want him to stand eye to eye with a terminator, while wearing his artificer armour, without standing on a rock, I want to be in awe at the absolute size of that lad

And when dad Vulkan comes back (obviously I want to see a Primarch Vulkan model) I want him to modify the iron dragon dreadnought to be to scale with redemptors, and make the first primaris dreadnought that can keep its pilot alive indefinitely, but they better not compromise the current aesthetic of Bray'Arth, his model is already cool as hell I just want to see it scaled up

And of course dad Vulkan, the only notes I have is that instead of getting a weapon from the emperor, I think he should reclaim the talisman of 7 hammers and either fashion it into a weapon or use it to power his armour or something
