I agree that its irregular that the first measure is pasted in the existing one 
and the rest are not.
But that is the only irregularity I see. Paste should check and do

(if singlestaff
        (if clipboard contains measurebreak anywhere
                (no new measure)
                (new measure)
        )
)


Otherwise its exactly what paste normally should do: Insert the clipboard 
between the last and before the next item.
On the other hand its not complete, and this is where you are right. Normal 
texteditor behaviour is that if you paste and there is a selection existent the 
selection gets replaced with the clipboard content. This is the additional 
functionality that is needed for your empty measure example (is it possible to 
select empty measures yet? and is there a graphical feedback?)


Luckily its no problem to trigger that behaviour with an altered 
SingleAndSelectionSwitcher. (I need to write a "delete the selection" for that 
first.. this is just a reminder for myself)

P.S. with any new command that allows the user to quickly replace, alter or 
delete big parts of the score UNDO becomes more needed. I personally don't care 
how its done, it could be quite dumb and slow for starters, maybe even working 
on a file-basis, saving and deleting snapshots of the complete score/movement 
insert the gzipped .denemo.
