Is it possible to change mask thickness without affecting other masks on a single Layer/Effect?

Description of Problem:

While attempting to implement the stroke-effect to a title I noticed that for some letters I needed the width of the masks to be different for some letters, and bigger for others in order for it to look proper on different parts of the image.  However, the Brush Size on the effect itself changes every single mask on the layer at once, ruining the effect in some places.  So that isn't currently an option unless I can find out a solution.  A couple of ideas I've had so far (please tell me if there is something wrong or a better option):

1. Create separate masks with differing thicknesses individually (independent of the effect) then apply that one effect to "All masks"

2. Add a separate Stroke Effect for every single pen-stroke while keeping the masks for each the right thickness.

I'm running into some weird problems when trying to test these different ideas out though:

(A) The effect just stops working completely if I have more than one effect (targeting different masks).

(B) The effect will only show one of the letters being animated if I add multiple stroke effects.

(C) If I apply the single effect to all the masks there's no way for me to go back and modify the thickness of the masks individually later on (that I know of).

What's the proper way to go about doing this?
