drop the plasma pistol on the apothecary and hav a plasma gun in that squad, if poitns allow bolter-melta combi would be best for apothecary.

As you know i use them a lot and to have one wielding a plasma pistol is just a point waste, i tend to gear them up with pwr wepp, melta bombs and maybe bionics.
Plasma gun would be more worth it with the apothecary as you can save the shot that overheats unless you lucky enough to overheat twice. In fact drop the pistol altogether as well as the meltagun for a plasma gun.

Bikers! with plasma! waste. Drop it give them summat more fun like err FIRE!!
