Sweet. I'm going to try out Peter Ps abstraction.
Additionally, I know this is not what you are asking for, but there is iemlib [fadtodb] and [dbtofad] which matches the default "MIDI" range of a slider to that of a VU in dB or conversely. I use these to match a control vslider to the same height as a vu for my faders.
There are also some simple channel faders: [g_chan] & [g_chan2]
