The issue will be with the new bars, is that they will be about 3 cm lower unless you get the longer stem to go with the new bars, which gets expensive.
Also dropping the bars will mean that the cables will need adjusting as well.
I must confess having seen the new 2017 bikes, the new shifters are really nice and given where they are, you can turn the bike upside down which you cant with the older style shifters.
