I think the problem you have with long scale strings on a short scale bass will be that you don't want the outer wrap of the string to be bent around the tuner post. I'm not sure how they tack the end of the winding down on a regular string (must be soldered or pinched down), but there's nothing holding the speaking part of the string on the core but the tension of the wrap.
If the outer wind gets bent, then it can cause the windings to unravel, killing the string.
On an Alembic, you have a problem with the E string because the tuning head is close to the nut (certainly less than the 4 difference in scale length!). You may have a problem with the G string too since it's also close to the nut in a 2+2 config.
It's not an issue for an Alembic with brass nut, but on a Gibson EB bass, you'll stress the nut too if the fat part of the string goes into the tuner.
