I fully agree that if you have to make the jump, a used or discounted Stage2 is the best choice, the ClassicEX is only a marginal improvement, while the 2EX is awfully expensive. The 2 gives you the best bang-for-buck right now, by far.
large grand = 80-100 Mb1 x LARGE grand, 1 x the LARGEST CP80, 1 x the LARGEST WURLI, plus the CLAV and a couple of RHODES (the latter two are both under 10MB each).
CP80 = 60 Mb
Wurli 2 amped = 24 Mb
Clav = 6 Mb
Rhodes = 10-15 Mb each (only #7 is significantly larger at 30 Mb)
The total of your wishlist is 200-230 Mb, barely half of the Stage2's piano memory.
You can fit all you want, add all the other Rhodes models, AND still have room for an XL piano (or two Large, or 3-4 Medium...)!
You can breathe freely, you definitely don't need the 2EX dude!
