Multiple Face Swap High-Res Photo

I have a single photo and want every face in it replaced with faces from another image, purely for personal enjoyment. Accuracy matters to me—I’d like skin tones, lighting, and perspective to feel natural so that the final picture looks as if it was captured that way in-camera.

Please deliver one high-resolution file (PNG or JPEG is fine) that is print-ready without visible artifacts. If you prefer working in Photoshop or a comparable editor, that’s great; I only need the finished image, though I’m happy to receive the layered file if you think it will help me make tweaks later.
