My idea is a site that shows old/fat men with gorgeous young models. (I'd like to point out that isn't a reflection on my physical being

I'm looking for help in a few areas,
1. What do people think of this niche, worth promoting, problems/pitfalls?
2. I'd be looking to buy up existing content before comissioning my own, so does anyone have any existing shoots that may fall into this niche that they'd be willing to sell. I'd prefer non-exclsive to start with to keep the start-up costs down.
3. Models - are there any male performers that would fit into this category. Can anyone forsee any problems getting females to perform with er, less attractive individuals?
Thansk for your help
