"these classes" being the ones deriving from Pair?  Yes, probably 
easiest to keep the changes from long etc. to sal_ as localized as 
possible, even if that means the clean up of the surrounding code still 
needs to be done.

One way to highlight those "intermediate" conversions is to use 
sal::static_int_cast (sal/types.hxx).  That potentially helps to flag 
those conversions in the code that can be removed again when all code 
consistently uses the sal_ types.
