I've wondered about this since watching Reichenbach. And I DO mean seriously considered; both canonwise and Moftiss adaptation-wise.
WOULD SHERLOCK DONATE HIS BODY TO SCIENCE ONCE DEAD?
Now think about it; first off we have a supposed death. Who would have handled the question of donating the body either for 'parts' or to science? Probably Mycroft.
Now yes, he wasn't dead but when he comes back, I would LOVE to see (after the initial reactions) John address this with Sherlock.
After all, he experiments on bodies donated for scientific purposes. I am sure he understands the worth of these donations. I am sure he would explain it as using the 'transport' for better purposes than simply taking up space in the ground or in an urn. It makes pure logical sense.
Now for canon Holmes, this option wasn't widely available although people DID do it. As a mature scientific man I can really see that he WOULD do so.
But BBC Sherlock is younger & still needs to mature. He has an ego that is less in control than Canon Holmes. I think it would be fun and interesting as to how he would anser such a question. After all, he knows first hand what happens to these bodies.

Mycroft’s popularity doesn’t surprise me at all. He is, after all, incredibly beautiful, clever and well-dressed. And beautiful. Did I mention that?
