Hi,

A layer mode is a formula for blending two pixels together, producing a 
result pixel. That is, the set of all layer modes is a subset of the set 
of all filters that blends two layers together, producing a result layer.

There is one exception to this nice classification of layer modes; an 
output pixel when using the Dissolve layer mode does not only depend on 
two pixels, also on the position of these pixels.

Spontaneously I don't think custom layer modes is a good idea. Might be 
fun for programmers to play with, but graphic professionals?

HTH,
