I find your argument a little confusing. If one did as you say and merely twisted the cartridge in the arm while keeping the alignement of the arm WRT the groove tangent the same, you would create very little force, as my post above explains.
The force you do create would be because the cantilever was bent out of alignment and the suspension is trying to force it back. This force is very small compared top the true skating force and with good alignment it is even smaller.
