The Multipurpose handle

So in looking at how I want to display things I had an idea about how tools will be displayed.  I am taking the perspective that the aliens in charge only wish to provide the most basic equipment to the humans, and many things are in reality virtual objects.  So as far as actual physical objects go every player will have the suit and an all purpose handle.  For the three main modes that will always be available for players in the field the handle will  change what kind of output it gets.  I envision this handle being somewhat like a WII remote in size.  For ranged weapon mode a glowing pistol/rifle will be attached, with the handle being the handle of the weapon.  For melee weapon/tool mode a glowing blade will appear on the end of it.  In placement mode a beam of light will come out of the end of the handle and whatever object the player wishes to place will show up either 1 a wireframe of the object in the color of the faction to indicate that it can be placed there or 2 a grey wireframe to indicate that it is a no go at that spot.  The last mode I think I want to have is just the laser pointer with the option of visible beam and invisible beam(it will default to invisible) which will help players to quickly communicate if they see something that they wish to draw their teammates attention to.
