After not rating the EpicUK Plaguehound Titans all that highly a couple of test games including one changed my mind - horrifically short-ranged guns but horrifically nasty once they get close enough!
In keeping with the highly-converted aspect of my Death Guard army and inspired by some conversions of Cryx models on the Taccoms forums I started keeping an eye out for some cheap Bonejacks to use as the chassis. Here's the first mockup, done a couple of months ago. Suitably bulky and the sculpting style is surprisingly close to the the Jes Goodwin Reaver head.
