The question is what do you want from this feature. The LVM would be 
able to provide you the ability to adjust the size dynamically. loop 
device is not part of this game. It offers you build the kernel or fixed 
file only. To append the number of null will make the system to be 
reformatted again to me.

I don't think we can do it.
