You might also want to check into Pyramid strings. Their "long scale" (at least on some sets) is 36".
Alas, per their latest catalog (
p. 15), Pyramid only makes their flatwounds 36.4" long ball to silk: the roundwounds are 37.4".
@ugly_bassplayer:
Warwick* makes long-scale string sets that have a 36" winding length; unfortunately, they only specify that for their black nylon tapewounds: it is not certain it applies to other product lines. Still, you could try one of their Red Label nickel-plated sets (they're inexpensive and well-received)
Warwick Red Label Bass String Set, Nickel-Plated Steel - 5-String, Low B, Medium, .045-.135 | Bass North
and see for yourself whether or not they fit. Failing that, I'd certainly try the bushing trick.
* [They also happen to make off-the-shelf medium-scale 5-string sets, but per the same information they provide regarding their tapes, these may be too short for you, i.e. only 34" ball-to-taper. They're also harder to find. Their USA online outlet has them
Warwick Black Label Bass String Sets | 5-String | Medium Scale | Stainless Steel
but the Canadian distributor they point to

does not.
Speaking of medium-scale fiver options,
there is also a single D'Addario low B (XLB130M) you can purchase at their website;
and also a (possibly discontinued - I can only find it in European stores) Dunlop set, part no. "DBSBN45125M"; similarly to the Warwick set, both of these alternatives are probably too short, at 34" winding, for the OP.]
