Hey, why not 5.1GHz @ 1024 bit sample rate? Do you really think that this would sound better for you? Hahaha...sorry, but I believe that you don't know a special physical fact:

The ears of a young child can't hear more than 20KHz (max. 22KHz). My ears (I'm 37 years old) can't hear more than about 16-18KHz and this ability will faint more and more.

Also the same with the resolution:
You won't really hear a difference between 16bit rate and 24bit rate (and more) because of the same reason. But if you really think that you will get better with 192KHz@24 then go your way. I don't want to hold you. But some day you will see that your HDD isn't sufficient enough for your recordings....and that's the only effect you will really notice...

Believe it or not!!!
