I don't even think Qui-Gon's view of the midichlorians' relationship to the Force was the prevailing Jedi view on the matter. It was established in dialogue that he'd clashed with the Council before.

I think it was more to do with the fact that he took more creative liberties with his role as a Jedi then the vast majority of conservatives would find comfortable. E.g. The kid is too old so why did you bring him in? He acted on his feelings and whims, something most Jedi were told to never do.

The other thing with clones is that force sensitives of the same dna start a feedback loop when together, Luuke was beating on Luke quite easily for that reason, despite the former being c'broths meat puppet.

I'm of the opinion that the Jedi at the time misunderstood the midichorians by attributing the source of power to them rather than them being a parasite that is attracted to the Force in living beings. So adding midichorians would do nothing to add or increase a persons Force ability.

On the other hand, I always thought it was kind of a keen idea to have a mad scientist come up with a virus (or whatever) that specifically attacks the midichorians. Someone with a beef against Jedi? An elaborate assassination attempt against Palpatine? Who knows, but the idea is pretty juicy and full of story.
