Probably be just a little on the wide side, but definitely playable. There was a Distillate 8 sold a few months ago that had been reset as a four. In an ideal world, you'd probably want a nut and bridge replacement to better position the strings across the neck, but I am sure it would function if you just pulled out the octave strings. You may need a truss rod adjustment when you take that extra pressure off the neck, too.
That's a beauty of a bass and I wouldn't worry about early bids in the $1000 range. This thing is probably going in the $5000 vicinity, maybe higher, and those little early bids won't make a difference. If we see $4K tomorrow, then I'd agree about the early bidding.
