Depends. You have to start with a reasonably low crosstalk, otherwise
combining the signals to separate the strings requires too much gain
and will be very sensitive to small variations in the crosstalk.

Another potential problem with this is that the vibration of a string
is the sum of two components: a vibration to/from the pickup, and one
orthogonal to that direction. These two modes could very well have
different crosstalk coefficients. If that's the case, separation of
the signals becomes almost impossible.
