Just take into account, whilst i would always rebate the handles in (or cut the laminate edge upto the handle), i would also forewarn the end user, that it will limit your options in the future, if you ever need to replace the handles.
There is some pretty average quality handles floating around out there. Your fronts will now be tailored to suit whatever you cut in - a replacement can be a drama, especially 5 years down the track.
