I think you're pretty close. The only things I'd recommend a second look would be:
The Raffles case with sapphire crystal means the crystal is easier to remove without damage if you're going to use the Sternkreuz crystal. If you're not changing the crystal, the acrylic isn't bad. The cases are the same otherwise.
Jubilee isn't the traditional bracelet on an Explorer, you'd want a folded or riveted Oyster (or a fabric/leather band) depending on the era you're trying to reproduce. That said, it's more a matter of personal preference, and if you like the Jubilee better, you're the only one that has to put it on every day. The Explorer was marketed as a more rugged sports watch, which is more in line with the Oyster bracelet, the Jubilee is more intended for a dress watch, but today, anything "Rolex" is considered jewelry, rather than a tool, so maybe the Jubilee is more appropriate in context.
