It will work just fine with a couple of caveats. One, there needs to be a
goodly sized filter capacitor at the junction of the 100K resistors. If you
can stand a couple of seconds "warm up", a 100 uF will serve admirably.
Two, if the noninverting inputs (+ inputs) have any function other than bias
(i.e. if there is feedback to them or they are an active input) then yes,
you will need some sort of isolation resistor network. How you gin that
network up and keep voltage drop from happening is up to you.

Usually, two 100k resistors across the supply, their junction
connected at the non-inverting input, alows an op amp to run from a
single supply, the output floating at about half supply volts. This is
fine for my use, but will it work with a dual op amp?
