[U-Boot] Cloning, Maybe silly question

[Pink Boy]

I have a suggestion/question.

Would it be easy, hard, silly to add a CLONE command to the make 
file?  (Are a separate make script?)  So if someone wants to create 
a new board based on an existing board they could just type,

make CLONE at91sam6263ek_CONFIG myboard

or if it's script 

./clone.sh at91sam6263ek_CONFIG myboard

The make file would clone the at91sam9263ek board configuration
and put it in a new directory called myboard and update the 
makefile?
