Yes ! But the input bias current needs to significantly less.  All input current goes to the output, and the output voltage goes inverted to whatever it can, to null the input differential to the fixed reference on VIN+.


The VIN+ determines the value of VIN- when it is used for negative feedback.   When the VIN+ is fixed, the inverting input is the only version to "sum current" with independent gain control of voltage.   The opposite does not sum current as in independent voltage summer, and that’s the fundamental difference, because the Vin+ moves with each change whereas using Vin- for "Sum input" remains fixed Vref=Vin+
