Technically the answer is "yes" you can do this but you would need to write the Gizmo from scratch in XML. This is not something that can be built in the editor and is a very advanced feature of HL. Not something I would recommend anyone starting with.
For something easier you may wish to look at the dorje from Ultimate Psionics in the
3PP Pack which is a type of wand but for Psionic Powers. Its not as cool as the Wand gizmo but allot easier to work with.
