Related to this, I would love to have a function that would enable me to
create a layer mask from alpha channel or apply it to the existing mask.
That way it would be possible to increase opacity with a layer mask by
first applying the alpha channel to the mask and then 'darkening' the
layer mask.

To me this is a missing link between alpha channel and mask. We already
have similar function when working with selections/channels.
