I know its not necessary in the slightest, it may even be impossible, but it would make a cool way to strip components off the board.
Hmm, I don't think it's possible to run Atmega328 with 27 MHz and as far as I know, the prescalers is only for timers etc? But I gotta admit, that I have never looked for that feature.
To be honest, I don't think it's worth the trouble even if you find a fancy way to do it. Especially cause 27 MHz / 2 gives 13.5 MHz which is not close to 16 MHz. It will give some new trouble with UART speed etc.
