Hi Jeff,
if I got your question correctly: your *_sn.mat warping parameters can be
applied to any image with any voxel size and you can choose the output
voxel sizes as well. It is common practice to apply *sn.mat obtained from
a highres to lower resolution scans.

The path of least resistance would be to co-reg+reslice the anatomicals to the functional voxel size, but we're trying to avoid that because the high-res anatomicals are being used for another purpose.
