It could be a good idea...
However, I must say that I don't like how Microsoft did it into its calculator plus.
If I will did it, I would like to open a child dialog box with selections for class (currency, distance, weight, etc), type for input number (example: American Dollars) and the type for output number (example: european euro).
If you will press a "convert" button (or you will type its shortcut from keyboard and the conversion dialog box is open), the value shown into into the output display will be read and then the result will be transferred to it.
So, I can add a voice into the "View" menu for enable/disable the conversion dialog box. This thing is a bit different from the layout originally made by Microsoft, but I think it should have a better pratical usage (it works with both standard and scientific layouts) and it's easier to implement and maintain.
Some opinions from other users about this topic would be good, because in reality I'm not a true expert of "designer of user interfaces"...
