If the two asset share the same morph targets names it should work by default, because the curves are just setting the 0to1 values of that morph.
If instead the names are different between the two asset, you can match them in ABPby using a ModifyCurve node, here is an example of blend shape matching between ARKit ( eyeBlinkRight ) and a CC3 character ( eyeBlinkR ) I did a while ago.
