No,kits are tested to work together,mix them and you might get problems. They may use slightly different binned ram or even soldering could make a difference.
Just use a 2x16gb set which probably would put less stress on the memory controller. Am not going into an argument about he size you want,never had to use 32gb myself,but if you think you need it fine. ;)
If you like all four slots occupied look at 4x8gb.
