Suspended pickup blues...

I have a Silvertone archtop which I love, love, love. Of the dozen-odd guitars I have, it is my favorite. I’ve been thinking of electrifying it again; the pickup had been removed when I purchased it. It obviously had something like you’d see in this auction attached to it.

In looking around, it seems that there aren’t a lot of options in the low-clearance department for suspended pickups. What’s the skinniest little bitch out there worth a shit? Surely someone here has done this, or something similar. I don’t want to put a Fishman or other vibration transducer type pickup in, because the sound isn’t at all appropriate to what I do. I want a floating humbucker, basically.

EDIT: This place seems to be the joint. That Armstrong 2-D might be just the ticket. A little more than I wanted to spend (it is, in fact, three times the cost of the guitar)… I’d still rather go with a vintage solution, should one present itself.
