ADA4927 minimum Vocm specification

Hello!

We are using ADA4927-2 with only positive power supply (+5V). According to the datasheet and also to the Diff-Amp calculator tool the minimum allowable Vocm value is 1.5 V. We need to set it to 1.25 V due to the following ADC requirement for optimal performance. Can we do that? Are there any drawbacks? Note that the voltage swing is maximum +-300 mV, so we are safe here. Please help to clarify this.
