Using 2 Isolated Power Sources

Is it possible to use this IC with 2 isolated supply?

For example One supply of 24V between V+ and other and the one Vloop of 12V. the collector of the external transistor would be connected to Vloop instead of V+. The idea is that if Vloop isn't providing enough voltage for compliance (V+-IO > 7.5V), the IC could be powered by another isolated supply. Would that work?
