Star Alliance - Award ticket question - routing on (relatively) new aircraft

Having just completed a trip in F to DPS and back, I've now got the bug to try some other experiences. Recognizing that the soft product is also important, this question is about award routing based on the hard product. I'm interested in trying to put together an itinerary that somehow (magically?) flies me on the 748, A388, and 787 all on one trip, sometime this fall (obviously on *A). Is this possible? I'm out of SFO, but can position anywhere to start.

A few givens: yes, I know that availability is a key consideration here. I'm willing to absorb the cost of award ticket changes (going away soon as my status improves), even up to the very last minute (LH, anyone?). I also recognize that this is a high risk endeavor -- aircraft changes are always possible. Finally, the final destination is less than important than how I get there. I do enough trips to nice locations that this time I'm more interested in joy riding these new planes.

So...any ideas for how to route this? What would you do to travel the world on new planes?

It will be tricky but if the stars (no pun intended) align, you might be able to do:

SFO-IAD-FRA-NRT-SEA-SFO

IAD-FRA would be on the 748, FRA-NRT will be on A380 (both Lufthansa) and NRT-SEA would be on the All Nippon 787 if you take the trip after October.

UA will have the 787 on DEN-NRT starting in 2013. ANA has it on a few routes as well. The 748 is only going to be via LH and they are moving it around a bit in terms of scheduling. And the A380 should be available on SQ, LH or TG (though SQ F awards aren't going to happen).

It really depends on where you want to go and what you want to see but getting all three in a trip shouldn't be too hard.
