Need some ideas for a Dark Mechanicus kitbash

[tuco]

The army I'm working on currently is a Dark Mechanicus army for lack of a better term.  The back story is that one of Cawl's adepts swiped the Primaris recipe and used it on himself (this was an excuse to bash the Techpriest Dominus and AoS Slaughterpriest kits togeher for my Warlord without having to be annoyed at the scale difference) then ran off and joined a World Eaters warband.  I'm using CSM rules for the WE legion and building a lot of my own stuff.  I'm going to be bashing the Bullgryn box and the AoS Stormfiend box to make a counts-as Daemon Prince.  

 

Where I'm hitting a bit of a wall with this is if I want wings how I would go about that.  I feel like perhaps using the wings from the Daemon Prince kit wouldn't really match the look of the mini when I'm done (I'm going for an "alright, who mixed up this brutish daemon with this piece of industrial equipment?" look).  So, can anyone come up with anything off the top of their head, preferably from GW's plastic kits since I find those the easiest to work with.  I'm thinking something that might work for wings from a vehicle perhaps, but haven't come up with anything that wouldn't seem too large.  I tried a few years ago for a somewhat similar mini for another project that was an Ogre Kingdoms mini with a rocket strapped to its back and used part of the engine for a Space Marine Landspeeder, but it never really came out looking as good as I had hoped.  I'd like to do better pulling this one off if I can.

I am using the rotors from a death guard bloat drone on mine.

I didn't even consider that because so much of the Death Guard stuff looks so Nurgle-y. Looking at them I think they would probably work. As an added bonus I have a Dark Imperium box with untouched Nurgle sprues, including the Bloat-Done.
