Hey E,
The FJ ICON shield tip you mentioned allows for the most custom options of any shoe in MyJoys. You can not only choose colors/patterns for the saddle and accent (toe and heel areas), but, as you hoped, you can also choose from about 44 base colors/patterns, including the combinations you mentioned. In total, there are over 770,000 possible custom combinations for the shield tip! I'm a big fan of the patents as well. They add a great pop to any design and I think you're idea of the cream/black patent sounds great!
