@hushrong: I wouldn't, it is a love or hate it thing.
So I started work on my Noxious Blightbringer conversion:
Helm from Heroes season 3, (his) right shoulder* and belly from Malignant Plaguecaster, reversed the bell and put a spare horn from a Lord of Contagion shoulder on (his) right side.
Base is a cast from Wurmspat.
I'll probably replace his hand held bell head with the one from the Plaguedrones kit. I'll need to optimise positioning, a bit of green stuff in the shoulder joint, add grenades etc. Lots of tac still.
But not a bad start even if I say so myself.
*this needs changing or the small horn cutting away or it would collide with the pack horn.
Looked at tring to cut down 32mm cast bases for 25mm Pox Walkers - just doesn't work, bases that small it looks wrong - I'll just use micro slate/sand mix above and textured technical paints.
With 10 unique sculpts from DI and 6 from ETB I just swapped parts between the four duplicates. Differing paint schemes will help, I just don't find Pox Walkers very exciting.
Note the Malignant Plaguecaster, Noxious Blightbringer, Plague Marines x7 and Pox Walkers x20 come to PL26, so we'll have to see what happens to those in Chapter Approved, my gut is I'll have to drop 10 Pox Walkers with suspected PL increases when 9th launch is base lined.
