The wording of your question implies it hasn't already been done. The fee was lowered to its current value when Bitcoin exceeded $20 USD per BTC. At this point there is no reason to lower the fee further. Maybe when 1 BTC = $100 then cutting the minimum fee by 80% would make it equivalent to the prior cut.
Still the min fee is likely going to be less and less important in the future. I already pay about 5x the min fee (still a fraction of a cent). The min fee doubling or being cut in half wouldn't change anything for me.

I know the transaction fee has changed before. Transaction fees will be very important towards miners fee's in the future.
