That site has a good list of wildcats but the 'can be made from' comments are quite simplistic; most of the listed cartridges can also be reformed and made from quite a few other cases than the one that's suggested. Best solution to find what can be made from what is to simply check the head/rim diameters and length of the cartridge of interest and compare that with what's available. If a match is possible, anyone with the experience and skills to reform should have no trouble finding a case match they can work with.
