I struggled for a long time to make a new-sculpt version of Tripwire.

It wasn't until I got a BTR Blowtorch, however, and had modified that to be my mainstay of that character, that I looked at the first new-sculpt Blowtorch and saw potential.

A head swap, a few helmet mods and some gray paint later and I had my jittery explosives expert.
