I don't think that's possible because the Schroeder SQ is a version of unipivot arm and it cannot "move" the extra pivot. The only way to retain the string concept is to have a servo linear slide. Frank is a genius so he might be able to come up with something that combine the two methods but I don't see it to be practical. However he did make an experimental string arm in the form of a Thales concept with a pivoting headshell before. Even though it still achieves tangential tracking but it behaves dynamically different from the LT model.
