TD, I'd make a typical starter, maybe 1.050 or 1.060 (a little higher than typical) with any DME and get that spinning on a plate with a new vial of yeast. Aerate it well. After a short duration, add some of the doppel to it. Say for instance, you make a 2L starter, add 1L of your unfinished doppel to it after 12 hours or so, let that spin for a bit and then pitch the whole thing at high krausen. My times may be a bit off, you'll have to judge for yourself based on the activity of the starter. This will get it slightly acclimated to your unfinished doppel, but won't stress the yeast too much initially. I've had luck getting a few extra points out of a beer by doing this - I'm not saying this is the best way or the right way, but it's a method I've used with a little success. The key is to get active yeast back in the beer, but active yeast that are somewhat used to the environment you're putting them in.
IMO your only other option is to pitch on a healthy yeast cake from a beer that did attenuate fully (something you probably don't have). I haven't done this, but I've read on here that some people, that's the only way they can unstick a stuck ferment.
