Could you build this?
No Emulating x86 architecture and translating Win32/DirectX API calls to WebGPU/WebAssembly in a browser sandbox represents one of the most complex systems programming domains.
What it would actually take: Requires an x86/x86-64 binary translator (JIT or dynamic binary recompiler) compiled to WebAssembly, a reimplemented Win32 user/kernel subsystem (like a minimal Wine in WASM), and a DirectX (Direct3D to WebGPU) translation layer similar to DXVK or vkd3d targeting WGSL. Developing this requires deep expertise in CPU microarchitecture, GPU graphics pipelines, and OS kernel emulation.
