Persimmons are extremely popular in Texas as the rootstock for them grows wild there. Another good one is Pawpaw, who is currently underway for some good varieties. There are tastings for pawpaw all over the southeast and you could potentially ask those people to ship some scion. The juicy factor is covered by peaches plums and the lot. Oil rich comes from almonds and hazelnuts. Creamy is pawpaw. You could also try maypop for flavor, but is kinda unreliable. Seabuckthorn is a good source of vitamin C and very sour. There are others as well like kiwi cuttings, chinese date, pear, che cuttings, mulberry, fig cuttings, and goumi. Of course you can get all the stone fruits you want, but looking at your list, it'll be tough.
