Why reprogram the arduino when you can just buy a crystal for 2 bucks
Personaly I have a box full of old crystals I'd like to use up. As I am presently at a river mouth about to head to sea I would have to allow two days to tie up ,catch a cab 40Ks to the parts shop, buy my crystal and catch a cab back.
I find it cheaper to reprogram it.
Its all a matter of your own circumstances and then how narrow or broad your vision is.
Marvin I am using a 14.890MHz crystal in an ATMega8 because of the above . To get the chip to run I have to change the Makefile and recompile the bootloader allowing for this crystal speed . I also have to create a board in "boards.txt" to get an entry for my board
If I program the chip with a sketch in a standard duelmilanov board with a 16MHz crystal and put a standard bootloader on the chip first it will all go off OK. When I put it back in my experimental board with the slower crystal the sketch will run just a little slower but not that I can notice ,however I cannot upload another sketch to it unless I put it back in the standard board
