You may want to check with Bayou cables. They do a lot of different cables, including custom. I’ve purchased a five pin cable from them for my Alembic. Great cable and decent price. I suspect they have done OBEL cables before. Of course you could get yourself some wire, a TRS plug, two TR mono plugs, some shrink wrap, and make one yourself. It’s fairly easy.
Another option would be to use a breakout box like the HubBub, or make one yourself. The advantage to using a breakout box is that you are then using one standard stereo and two standard mono cables. If anything went wrong with a cable at a gig, for example, you could easily replace it. If a stereo to double mono cable fails, you are SOL unless you are carrying a backup.
