Separate alpha and RGB specifications of line colors.

Currently (version 4.7), the specification of the alpha channel of the line colors is bound to the RGB specification: #AARRGGBB. This means that one can't adjust the alpha "on the go" with predefined color names or linestyles. For instance, I have scripts that define various linestyles. I would like to be able to use those defined linetypes (i.e, not to have to write out each color's RGB) and independently specify the alpha:

plot sin(x) ls 1 alpha 0.3, cos(x) ls 1 alpha 0.8

It would be great if you could separate the alpha and RGB specifications.
