Default Matching Pmosfets with source resistor

Hi all,
just measured my 32 Mosfets and grouped them into sets of 4 for my new power amps. 4 pairs in each monoblock.
BUT 1 has a low Vgs.
Q. can I achieve a better match to its partners by increasing the source resistor above the standard 0r1 to say 0r33?
