Hm. What is the reason for this exercise? Switching to read only of top layer is not enough? Anyway, I think we can add this option to "resize" command perhaps. (Resize reloads mapping, so it can switch read-only flag as well.) But it can be dangerous in some situations... (And you can do it already using dmsetup but that's quite complicated.)
