Sometimes we can find the ideal cat to make all desired traits stronger at once or as much as possible.
I would work with a kitty you know it's hiddens from basically a cat you know or bred yourself or from a good friend who knows his/ her kitties well.
You may find an ideal kitty but it could contain all sorts of unwanted and recessive hiddens which may pass instead.
Indeed if you'd like to push away the chateau pink you can do this by using a more dominant fur than chateau pink and more recessive than the Moo Kitty.
What you would expect from their offsprings is that the moo kitty shows.
To catch the black whiskers you can use 2 tone to see if black came through.
If their OS-ers do not show white as moo is showing but 2 tone you know this is only possible if black has passed as their hidden whisker color.
Assuming black is what is hiding and not a more recessive.
The grandma Jewel allowed Black Whiskers to pass the question is what does she hide hopefully for you Black whiskers.
So you can also go for a cat with black whiskers shown.
To keep the vampire ears you could use indeed more dominant ears than soft curl or "better" to push that hidden more recessive away but where you are at now less dominant than Vampire so you can see when Vampire has passed and not Soft Curl or "better".
You'd expect from their OS to show the Vampire ears.
There is an extra hickup the very dominant passion eyes from which I assume you want to keep.
Grotto from dad is very recessive so I'd want to tackle that.
You'll need very dominant eyes to make sure the passion eyes remain to be there from their OS-ers you'd expect to see the passion eyes so the eyes would preferable be dominant but recessive to Passion.
From the OS-ers you would expect to see passion.
I think to make all changes you wish to this Moo you need mutiple breeding programs focused on eyes ears fur and whatnot.
Unless you have a qualified kitty you know inside out and which can do the job.
Ultimately you can make sure your Moo becomes a 9T but I'd say don't ask too much from them at the same time.
As for the pupil: from what I see in the pedigree I only see a big pupil.
It isn't to say that somewhere hidden may not be a small pupil this is very possible but for now lets assume you need to breed that in later on.
As for the tail goes yes the wild tail is new so you would work with a cat you just purchased from which you don't know it's history very well.
Maybe adding that tail can be the cherry on the cake in later instance when the trait costs less and you are able to find it on a fairly dominant kitty.
The furs you suggested to work with are very good dominant furs the only problem I see is that they are more dominant than Moo so for you there is no way to tell if Moo's fur passed on their OS-ers or the Pink+
So I'd go for an as qualified as possible cat with slightly more recessive traits than your desired traits so you can at least see if you are on track and if traits passed.
It would be wonderfull ofcourse if the kitty you are to work with has a small pupil and the traits you miss currently in the Moo.
Just so when you breed their OS-ers there are no inconvenient surprises and perhaps even 9T's.
The thirth generation is the generation in which you usually see if your plan comes together.
Good luck!
Edit Because it is the Halloween season you probably can find a black Russian (more recessive than moo) with Vampire Ears and Passion Eyes.
Breeding moo with such kitty makes the chances higher a lot of the by you desired traits pass.
Via this way you can slowly work towards your ultimate goal.
It would be awasome if that Black Russian had the desired Black Whiskers as well.
And preferable 9 traits.
