Sorry, but this theory will now be disproven. I give you the link of where as soon as KA is used on Itachi the sharingan reverts back to a three tomae.

Now I will give you 3 reasons of why your thesis is wrong.
1. What you are doing now is hearsay. Even if Shisui was able to "implant" his KA like Itachi did, wouldn't he have been touching Itachi like a poke or something.
2. Honestly, I apologize but I did not clearly understand the rest of what you were trying to say. It seemed like you were saying something like these people awakened a certain form of sharingan based on what happened right in front of them but than forgot the experience but remembered later on. There are also flaws with this.
A.
It was not Kakashi who "awakened" the Mangekyo, it was Obito. Since he is not an Uchiha, he still would not have been able to unlock the mangekyo no matter if he killed everyone in the village.
B. Your trying to base your theory on other theories. At least somewhere there has to be some kind of evidence of what you say is true, otherwise it's just a bunch of ideas that can never be proven right or wrong.
3. Even though at first you did put up a valuable argument, you are now basing your ideas upon other ideas. Until you can give some kind of proof whether what you say is right or what I say is wrong, either or, than we have nothing further to discuss. I have shown you that when the KA is used it reverts back to a regular sharingan. In the manga pic you have given, the last we see of it is taken out by Shisui's own hand who than says protect the leaf who then reaches out to give Itachi, he did not however "touch" Itachi as far as we know let alone have the skill to be able to do the same as Itachi did to Sasuke.
I hope this has been a reasonable debate and hopefully the new manga is out
this has all been explained , you're not getting the gist of it...theory isn't proof or fact, its theory, ideas...
alirght look this is all of it in a nutshell..
if shisui cast KA on itachi to protect the village
then itachi will do whatever he thinks is the way to protect the village...
he doesn't kill sasuke because Itachi knows sasuke doesn't know anything about the plot to destroy the leaf.
shisui's MS was still active the last time he went to see itachi so he did it there.
we never saw that MS deactivate while shisui was alive.
he gives it to itachi (not implant, maybe) and itachi keeps it safe and stores it in a crow..
you can still show emotion while under KA and other genjutsu...
if you are ordered to show emotion you will, unless you are ordered to be emotionless.
after KA broke Edo Itachi out of Kabuto's control, Itachi is still shown behaving like any regular person..
he even has conversations with multiple characters all throughout his time as an Edo.
He also shows emotion (as an Edo) to Sasuke and even Kabuto
and explains to him on how to accept himself and break out of Izanami...
KA is still cast on Itachi as he hugs Sasuke 1 last time before the Edo are withdrawn.
but how is it able to be used in 8 years time
if KA was cast on itachi and itachi didn't know about it
then he would still act as if it was never cast on him , in his mind it wasn't used on him
when he gave it to naruto via that crow. Itachi didn't look at the eye while he was giving
it to naruto , he just sent it through him somehow with the crow(like giving out chakra)
and already programmed it to work on his eyes if sasuke inserted them.
but if Shisui used it on itachi before the massacre, and it was used on itachi during the war
that would only be 8 years difference. not the usual 10.
how can that be used again then...well, I already explained it...
the crow with KA was placed inside naruto..with the 9tails..
the 9tails chakra has already been shown to speed up jutsu reactivation time with kakashi by giving more chakra.
and uzumaki are relatives of the senju..(I thought this was obvious to everyone by now)
and itachi has shown to program a jutsu to activate before it is even used once by the jutsu wielder..
sasuke used amateratsu on Tobi before he ever awakened it, because itachi programmed it to do so.
same thing with KA (shisui's MS eye & crow) itachi didn't know (??) it wasn't MS anymore
when he programmed it to activate KA on his own eyes implanted by Sasuke.
it was luck(??) that he gave it to naruto and it used kurama's chakra to reactivate quicker than
the full 10 years time length.
