I have two questions. The first is to confirm that Mind Blank makes such things as Nondetection and Magic Aura redundant, correct?
The second is can a familiar use the Partner in Crime reaction to help with the Convincing Illusion reaction?
Nondection can target objects while Magic Aura only targets objects (with bulk limit). Mind Blank only target creatures so altogether, it's not fully redundant.
I think that familiar combo should work. Aid triggers on an action, which a reaction still is, and the reaction the familiar gets is separate from yours so it looks like it checks out.

Pretty much, yes. Though since Mind Blank is an 8th level spell and the other two are 1st and 3rd level, I would expect Mind Blank to be a bit more powerful.

Looks legal to me. The familiar can Aid on a Deception check, which is what you are making as part of the Convincing Illusion reaction.
The only difficulty is in having the familiar prepared to Aid your check. Maybe Independent and have them constantly stay prepared?

That is actually exactly my plan!
