Family Photo Merge And Enhancement

I need two existing photos combined into one, featuring myself, Michael, and our baby. Please sharpen and correct the lighting. We do not need Michael’s elderly mother in the photo, as she is already in the first photo, we need to simply move Michael from the old photo to the photo of me holding our son, Michael is in that photo already but just barely. We need him all in there and we need to fix my face so that I do not look like a ghost. Thank you.

Requirements:
- Combine two photos seamlessly
- Moderate sharpening for clarity
- Natural light correction
- Convey a warm and cozy mood
