Could you build this?

No Patching Mach-O binaries, load commands, and private iOS Simulator device configurations requires low-level reverse engineering and deep understanding of Apple binary formats.

What it would actually take: Building this requires a Mach-O parser and binary editing engine (such as lief or custom C/Python scripts) capable of restructuring load commands (like LC_BUILD_VERSION) and Info.plist configurations. The hard part is reverse-engineering Apple's closed UIKitCore and Simulator runtime validation logic to discover undocumented platform and device family flags that trigger dual-screen foldable UI. This demands specialized knowledge in iOS/macOS systems internals, assembly, and binary reverse engineering tools like Hopper or Ghidra.
