You are not going to find mouldings in the exotics. There's no money in it for the distributors since the exotics wear out tools real quick. Sharpening straight blades for planers and jointers is one thing, but resharpening moulding knives that have gone through too many feet of cocobolo is not easy.
People who work with exotics a lot probably use more hand tools than machines BTW. Their goal is to get the thing to final finish with minimal recourse to sanding (which is not real easy with some of these ultra dense, ultra hard exotics). A super sharp moulding plane blade will yield a glassy finish when everything is done right.
Many exotics don't glue well at all thanks to the large amounts of natural oils and resins in the wood. Best results can be had by stripping the oil from the surfaces to be glued with acetone, then drying it, immediately prior to applying glue. Probably a mechanical joint will be more reliable, especially if backed up with glue or epoxy.
You can machine these woods, but you might have to expend some serious sanding time getting the machineing marks out. However, you'll probably have an easier time getting someone to route out the 16 feet of moulding you need on a router table, than you will finding a master craftsman or woman capable of hand planing the moulding into the wood with super-sharp moulding planes.
BTW, if you opt to do this yoursewlf, test cuts in scrap stock are invaluable. They'll tell you how fast you need to feed the stock to avoid tearout and excessive machinemarks, and ensure you get the settings and adjustments right. Light cuts are always a great idea with delicate work, and knocking off excess stock with a saw first can save a lot of wear and tear on your router.
A shaper is even better than a router for this application, if you either have one, can get access to one, or know someone with a shaper. If borrowing someone else's tools (especially and insitution like a trade school) buy your own shaper blades or router bits to ensure sharpness. Consider buying top of the line cutters to ensure the sharpest, cleanest cut.
Have fun
