Something's about Miss. Fortune

Now I love M.F., her being tied as my favorite adc along side Twitch, but I, and from what I found in the forums think she is lacking in some way, missing something that wold make her more unique, so I decided I would do a full rundown on her abilities and tell you guys to see if it would improve her in anyway. Lets start

Passive: Strut: Now we all now a big way Riot can help M.F. with this by allowing minions to not be able to disable it (which I don't really understand why its not implemented like this but whatever) but I also feel that that alone would no be enough so how about every 6 levels she get's a 20 MS increase of her passive allowing it to be more useful late game and not necessary just a way to get to lane quicker

Q: Double Up: Now I personally find this spell to be pretty much at best as it can be right now not being able to think of a way to improve, it except maybe if you hit a champion with it and said champion has more armor that the second one it gets armor penetration but like I said I think it pretty perfect as it is now

W: Impure Shots: Now this is were I have a lot of ideas on what it could do or at least be nice to see:

1. I think it would be nice if her passive Strut and the Strut from W being active stacked with each other instead of being the same Strut basically making it a (at first rank if my passive suggestion are to be acknowledged) 140 MS bonus, now this is not to say that it would help since at one hit by an enemy, or minion sadly would take it away.
2. Lets make it so the Strut active can not be disabled by any attack while its active making it so not even a champion or minion could take it away till the spell's 6 seconds are over.
3. Combine my two options by making her into a moving woman of bullets and death (Boots are made for walking comes to mind right now), now if these changes seem to be a bit OP hows about we make it so her passive's Strut is able to still be deactivated leaving her with just 70 MS from her W, if attacked.

E: Make It Rain: I really can't think of anything for this spell since from what I played it's OK right now, I mostly use it to check bushes so maybe increase the range a bit or, and this is something I just thought about, any minion that dies in it gives a bit of extra gold, or is that too much?

R: Bullet Time: And finally her ult, now I have seen many people say that the bullets that she fires should have to be related to her attack speed but I have also seen people saying that's more of Lucian's shtick and that it would not really do much but I have an idea which might be more interesting, we always relate M.F. to sweet wombo combos and since not all fights can be controlled by their position how about making the cone of her ult wider by rank allowing her to be able to hit more of the opposing champs easier even if they try to escape

So what do you guys think am I making her a bit op or are any of my suggestions good choice that you would like to see?
