Essentially 3dMEMA plays the role of differentiating the subjects based on their relative reliability. So yes, it would be still helpful to use the results from 3dDeconvolve as input for 3dMEMA for the differentiation purpose.

Just use the typical population analysis programs such as 3dttest++, 3dMVM, 3dLME, etc.
