An impressive torso going spare

I had a plan. I was going to convert my own version of Gabriel Seth using the Forge World Legion Praetor body and the two-handed chainsword from the Space Marine Assault Squad kit. It was a good plan that would have looked awesome if only the two components of said plan actually fit together.

You see, when I came to dryfit them together they didn't fit. The Praetor's torso is not designed like every other Space Marine ever with perfectly flat, perfectly parallel surfaces on either side for flat arm connections to fit on. Instead, I end up with a situation where gluing one arm has the other hanging wildly away and forward of the other shoulder.

Luckily, the random eBay purchase that netted me this torso also got me the Captain's body from the MkIII Legion Command set whose body does fit the arms. He'll be a little smaller but on reflection the twist in his body combined with the chainsword does give me a more dynamic pose as if Seth is bracing to received a blow.

This leaves me with the impressive, finely sculpted and suddenly useless Praetor body on hand. So here I dither, wondering what project to slot it into.

The knightly appearance of MkIII suits itself to making a Black Templars Marshall, of course. There's also the unit of Fallen I'm currently converting to accompany my Death Guard using Iron armour and a Dark Angels Veteran Squad who could develop a sudden Fallen Lord. The Death Guard themselves are already overflowing with characters and I don't want to do any heavy conversion work to the body itself, so that's out.

Then there's the project the MkIII Command body was meant for in the first place: an Alpha Legion officer to lead the Headhunters squad that will accompany (and be the only Astartes unit in) my resurrected Lost and the Damned army. That said, the Praetor body is a little too glorious to be Alpha Legion. I am not a fan of the Armillus Dynat concept, if you were wondering.

I definitely don't want to use it for another Flesh Tearers character, I don't want a random Captain going around looking more glorious than the Chapter Master.

So right now the options are Black Templars or Fallen, either way another excuse to fail to learn how to highlight black. Just depends on which character I can come up with the best design for.
