Here's a theory:

What if the XFA-24A is a prototype to the XFA-27 and the XFA-36A is a successor?

But here's the problem, the XFA-24 was developed way after the XFA-27. But could it be developed as a budget-based aircraft? The XFA-36 was developed after the XFA-27 no doubt, so it's entirely possible it's an upgraded version.

See, it's unknown who developed the XFA-24. It could be the same people who made the XFA-27. The XFA-36 was developed by General Resource (formerly Grunder Industries). So maybe Usean engineers made all 3?
