LM76005: Can output of second cascaded buck converter be used for external bias of first buck?

Tool/software:

I'm designing a circuit that has to convert 48V to 12V (LM76005, 5A), and 12V to 3.3V (TPS562242) using cascaded buck converters. To improve the efficiency, the LM76005 allows an external bias to be tied to the bias pin. I was wondering if it is possible for the 3.3V output of the second buck to be used as the bias input for the first buck, or if this would cause any feedback loop problems since one is dependent on the other. Here is the circuit:

Furthermore, any feedback on the schematic is much appreciated. The lead 48V wires are about 2 meters long. Thank you
