You know, thinking more on this, this is still a naked power increase.  I can stop V components by gagging or using silence[\i].  I can stop M components by removing a component pouch or preventing access to a focus.  I can prevent S components by binding.  How do I prevent visual, auditory, and scent cues?  These are not a flavor replacement for VSM, they're just flavor.  Unless, of course, I can prevent powers with an olfactory displays with windy conditions or lots of coffee, visual displays with darkness or excess clothing, and auditory displays with silence or a tuning fork (actually, that's a neat idea)?  I don't think this is your intent, so the displays are really just cues that a power was used, and not requirement to use the power.  A naked, bound, blindfolded, gagged psionist in a silence spell and darkness spell is just as capable (absent targeting requirements) as a non-constrained psionist.  This is definitely power creep.
