  Questions that have to do with mixed models will generally get
better answers on the r-sig-mixed-models at r-project.org mailing list.
I don't know the field of advanced response surface analysis very
well.  It sounds like you might need to contact the RSA package 
maintainer, and that you are likely to have to do a lot of re-engineering
from scratch.  Maybe as a shortcut you could figure out a way to
get robust (Huber-White/sandwich) estimates of the standard errors?
