this will work, but I am looking for something much simpler, based around 
say an op amp with signal A run to both pos and neg inputs, and sig B to
one input only, with a resistor network including a fet to ground so that
as the fet resistance is changed the op amp output goes from A to B
(or likelier A to -B).
Pretty sure this is 'doable'.
