Modify 6th gear of MT

Hi gang,

Has anyone tried to change out the 6th gear of the MT for one with a smaller ratio value (so the RPM at 80MPH could drop down from 3K to 2.5 or even lower)?

I'm curious to hear if anyone has tried that and if so, how stupidly expensive or difficult would that be to do? Thanks!
