Fork swaps are all fine provided they don't require major surgery to the frame to get them to fit.Do the stock forks have to be from the same frame?

Some have trimmed a 1/4" or so from a headtube to get the right length for different forks to fit and that has been fine in Class 1, but cutting out a headtube and welding in a different one would definitely mean a Class 2 build.
