Yes, you can open it in other versions of Blender above 2.92. For example, I have version 3.1.2 and I can open it. It's recommended not to open it in versions older than the one it was created in.
I'm glad you liked it. I have a male body model, but I haven't posted it yet. I'll do so this week if possible. Although it might not exactly match the style of the Body 03 model.
