If your front shifter is indexed, you might have problems if you start making changes as the indexing might not work well. That is why most of my bikes have a friction front shifter, I can easily shift with mis-matched front derailleur and crankset. My derailleur touring bikes use bar end shifters, the front shifter is friction.
