> could I use the same model that I've applied previously for this purpose, and just change my post-hoc GLT codings slightly?

In that case, you code the factor "scram" with a mixture of between-subject and within-subject types among the 3 levels. I'm not so sure if 3dLMEr would work that way. Does the program complain about such a specification? Even if it does not complain, try the approach I suggested earlier, and make sure the two approaches converge.
