It's not a Nuke solution, I know - but for this type of effect I usually find it easier to generate glitches out of After Effects. There's an old DigiEffects plugin called Blockade that looks a bit more fresh (and less overused) than the Rowbyte's Data Glitch, but it's definitely chunkier and less fine detailed. There's also one in Red Giant Universe that I've not tried.
I usually generate them as mattes and then layer them up so I can push them through hue shifts and other color mults - makes it a bit more design friendly and controllable that way. You can also generate some really nice textures by running out fractal noise patterns set to block. Another contender to sprinkle into the recipe is the classic "BadTV" plugin that I think was part of Tinder - not sure if that's even available any more or if it's been absorbed into Sapphire? Would be cool to see a nuke gizmo that could approximate some of those plugins and do it all quick/dirty and free!
