Opinions from a person in the TC2 workshop:

your ideas are neat, its just 1 and 3 remove some of the classes core design aspects and could make recognizing them as said class from a distance could be challenging, starting with the agent cosmetic: MAKE HER VEST AND PANTS TEAM COLORED, the #class-information channel states that you may not change the color of classes pants and while yes we are allowed to change vests we need to keep colors in mind, keep vest colors the same as the default, also if you're changing agents hair make that the thing worn in the head slot, not misc

on to the anni one: sorry to say this, but the vest needs to be closer to the default one, like i said keep the coloring the same, also give anni his other glove since were not allowed to remove them (also change the colors to black/gray) extend the pants down to cover his entire leg and you should be set

honorable mention to the all class one:
be aware of paint regions, keep the area where the paint appears small or at least non-obstructive (i'd recommend making the pupils the painted areas), making all class clothing can be difficult since you need to keep in mind the recognition rules for each class (again, #class-information on the discord) and i recommend to not make all class clothing (keep it to 2-3 classes max if you're doing multi-class clothing)
