They'd still have to create a new currency that way. And you can't force a value on that one. Sure, it could have the value you want on paper, but just like the current one - it wouldn't match the usage in practice.
Adopting another currency makes sense if it's easy to do a lot of trade using it. The closer you are to other $ users then, the closer the real value, because you can easily trade outside of the local bubble.
(It could work of course (and did for some countries)... but you still need to have actual well working trade to make sure the currency has the value you expect)
