In my case I was concerned it would take too long. I mean, attaching a ready-made arm seems like it would be a lot quicker than developing a technique to create a new one from scratch. Saving time that could be spent finding food and a way to escape.
You would think so, yes?
The issue is that eventually rumors will spread of a blond haired, sparkly, clawed, sharp-toothed ninja with the sharingan. The chance of another sharingan user outside of Sasuke (protected by the Leaf), and the S-Class Itatchi puts us in pretty much everyones crosshairs.
True, true. true.
I frankly don't see us as likely to get the Mangekyo at this point without jumping straight to a transplant, and therefore straight to the Eternal version, or otherwise cheating our way into it in a way that makes the degradation a moot point. We just don't have anyone close/important enough to us to qualify as our "closest friend" or equivalent who we can kill for it, and I doubt that we would be willing to do the deed if we did.
That's likely to draw the interest of Orochimaru as well as anyone else.
We can still do that after we get strong enough to dodge hunter-nin. Especially if we end up going with Orochimaru. Unlike Sasuke we won't have any great mission to do after going Sith Apprentice on him.
Sasuke didn't kill Itachi, just watched him die. Same with Obito and Rin. We don't need to kill someone close to us, just watch them die. And we should get on getting closer friends. I recommend Hinata. After our fight we're already basically rivals, by Shonen logic that makes us a step away from besties. Also, I think you might need to activate Mangekyo on your own before the transplant can take. No one seemed to use them unless they met the activation criteria.
'S possible, but it's equally possible that the surgery for the eye swap changes something in the chakra flow, or the eyes being technically foreign entities does the same. It would actually be pretty funny if it was actually the surgery that fixed it, and not the eye swap, so they would have been better served just cutting out their eyes and sticking them back in. That said, given how the Mangekyo Sharingan looks like a hybridization of the two "parent" Sharingan, I'd say the second explanation is more likely. It's hard to say really, biology is complicated even before you add magic.
That's highly debatable. Sure, Itachi technically died from his illness, but it only acted out enough at that moment to kill him because of the battle with Sasuke that had just put massive strain on his body (especially with his use of Susanoo, which is explicitly stated to put a lot of strain on the user's body) and drained him of most of his chakra. So Sasuke did kill him; he just unintentionally used Itachi's own illness as part of how he did it.
See: my crack idea for turning a mangekyo into an eternal mangekyo by transplanting your own left mangekyo eyeball into your right eye socket and visa versa.
I'll be voting for the latter.

Wonderful. Do you have a citation that actually says what you say it says? And that ISN'T a minimally-detailed website for basic information that can be freely edited by anyone with an internet connection? Because a wiki is NEVER a reputable source. EVER.
I was all set to congratulate you on having an actual citation, and changing my mind. Then I watched the video. Tobirama does indeed mention something vaguely along those lines as the method by which the base form of the sharingan is unlocked. Specifically, he says, and I quote: "When an Uchiha is tormented by the loss of a great love, or by despair at who he has become, or something equally terrible, a special chakra flows through his brain, causing his nerves to respond and his eyes to be altered. These are the eyes that reflect the heart, known as the sharingan."
Given how obsessive the Uchiha are about their eyes, they're probably still usable.
Even if they can't be implanted we could still use them for Edo Tensei.
Probably not a good idea, seeing as she died by wasting away in depression and apathy iirc. Being resurrected would be more of a curse to her than a blessing.
