No, right now this is not possible: you can hide some elements
completely (use Tools->Visibility), but not make them semi transparent.

You could generate a post-processing view from your mesh (use e.g.
File->Save as->Gmsh mesh statistics) and affect two different values to
two separate groups of elements. Then in the view's option, you could
specify a partially transparent colormap (Ctrl+click and drag alpha
channel). This would do the trick.
