If I'm correct (and again, I'm not sure I am), you would need to only
apply some procedure that uses the EM algorithm to impute a single
data set that would subsequently provide factor loadings that were
essentially the same as those obtained through the use of multiple
imputation, since the EM procedure doesn't add the noise to each data
set that represents the imputation uncertainty that the MI procedures do.

...again, however, I'm hoping that someone could either confirm that
I'm correct, or tell me where I'm wrong because I'm working on
something similar.

I said something similar, (1) compute EM, (2) use covariance matrix to
compute eigenvalues, etc. R
