The biggest problem I had with this is that you have to start a new campaign - which means you lose all your big clickthrough rates. It's a pretty heavy penalty for just switching billing methods.

Will Google have any serious issues with running 2 accounts at once (temporarily)?
If you hear from Google on this matter, explain what you are doing and why. I'm certain that you'll be given time to finish.
As you most likely know, Google's concern is to avoid more than one ad showing for the same advertiser for a given keyword search. So if you can avoid this, while operating the two accounts temporarily, all should be well.

A WORD OF WARNING
You may not want to leave the US$ system, why?
I found that if you often use the mimimum bid price, then the currencies other than US$ will not allow you to use the lowest possible bid price as Google set the mimimum bid price to something higher than the US$ price.
This can lead to you paying 10% or more for your advertising.
