No, sense is detecting and processing stimuli. I made that quite clear already. 🙁

Sensing light and dark and then colors in the visible spectrum is what comprises our vision. Turning another sense on that senses an organisms chakra and chakra flow and also having slight x-ray capability would be 2 completely new senses associated with vision.
Technically, those are two completely different sensory modalities.
And, why would you down play the Sharingan like that? Don't you think that's a bit absurd, dude? 🙁
You make it seem like a simply filter for the eyes when it actually makes the person one of the deadliest and most effective type of ninja in the series.
It actually gives the user 3 different senses:
Chakra sense: being able to see chakra.
Slight X-ray capability.
Slight precog/reactionary ability: being able to predict movements and react to them.
That's a total of 8 senses: 3 addtional. The 3 additional are above and beyond what Aizen would affect. Also, we already know that the ability to sense spirit energy is not completely blocked out because Yamamoto was able to break his illusion quite quickly against Aizen as soon as he was stabbed. That pretty much puts a nail in the coffin of it really being limited to those 5 senses.
You're getting hung up on "sight" being one complete sense when that really is not the case at all. Five senses do not include senses above and beyond the visible light spectrum.

That is certainly a factor (if I understand what you're saying). If Aizen fails to create the illusion of characters having chakra then they'd figure it out. Not that it matters becuase he could always just blind them if they rumble it, maybe get rid of their other senses too so they're effectively helpless. Knowing they're in an illusion won't help them much unless they have some way to brake out of it (idk, don't the Sharingan have the abilitie to see through illusions to some degree?).
Aizen can only affect the 5 basic senses: above and beyond that, he cannot. He was not shown doing that ever and he was shown affecting the 5 basic senses.
The Sharingan allows a person to be immune to Genjutsu, from what I remember of that fight between kakashi and itachi. However, Itachi overpowered Kakashi by using a higher-evel eye technique: the MS.
