You can add additional data from any source, providing you can figure out how to encode it as a restraint. If you want to (ab)use the existing EM restraint for this purpose, you will have to manually convert your data into something that looks like an EM map in MRC or XPLOR format - it doesn't read sca or mtz of course, because it is not designed to handle crystallographic data.
If you want to write your own restraint type, see http://salilab.org/modeller/9v7/manual/node427.html
