I'm not sure why you need the layer masks? Won't the following work a
little more simply or does method you suggest do something I've missed ...
1. Create new transparent layer, select it, leaving background visible.
2. Make rectangular selection to leave the border width desired (say 50
pixels) and invert ctrl+I
3. (optional) Select-feather choosing width half border width (say 25
pixels)
4. Select foreground color desired and drag to image. (will leave a
solid (optionally feathered) border)
5. Drag opacity slider to 50% or to taste.
6. If "happy" merge visible.
Quoting Lap1994 <[EMAIL PROTECTED]>:

I can't think of a direct way to do that but it can be accomplished
with a few extra steps.
* Duplicate your original layer (this will let you see the image as
you paint).
* Add a black layermask to the duplicate layer.
* Apply the layermask. (The layer will become transparent, but the
original color data is still there.)
* Choose your paint tool and set the Opacity slider (in the Tool
Options) to the level of _transparency_ which you desire. If you want
the border to end up with 20% opacity then set the slider to 80%
(fifty percent opacity means fifty percent transparency).
* Paint the duplicate layer. (You can toggle the visibility of the
original layer to see how the semi-transparent result of your painting
will appear; however, the unpainted regions will not be visible.)
* Add a layermask to the duplicate initialized to "Transfer the
layer's alpha channel" with the "Invert" box checked.
* Hide or delete your original layer.
