Just do areal distortion. It'll be easier to average the results. You can average them with caret_command's math function, but I find it easier to do it in the GUI. Load the resulting shape/metric files as metric, making sure one column for each subject is loaded -- areal only -- and do Attributes: Metric: Compute average...
