Yes, but you haven't gone far enough.

Each colour at a gradient node should be customizable through an
expression language (like in MathMap), so instead of gradients like
'Tube_Red', there would just be 'Tube'. The highlight for 'Tube' could
be 'hsv(fg.h,sqr(fg.s),sqrt(fg.v))', the shadow edge could be
'rgb(fg.r/2,fg.g/2,fg.b/2)', and the deepest shadow could be 'bg'.
Then you set the FG and BG colour and get a tube gradient based on
those two colours.

(Note that my sample expressions think of colour value on the range
0.0-1.0 so sqr() makes a value smaller and sqrt() makes it bigger.)

Just an idea :)
