No, the "time shift" effect that preserves the pitch while changing length
is the wrong choice.  The orignial problem is the slight difference
and drift in the sampling rates of the signals,m so you need a resample to
correct that.  A resample will restore the orginal pitches while the time
shift will preserve the mismatching pitches.
