How do you know if your plot ideas are a little too far fetched?

I have a lot going on in my planned story at the moment and I think it could work if I focus on the right pieces of it. The issue is that I’m crossing styles and ideologies that typically wouldn’t match up and I’m wondering how you make the decision that something is too ridiculous? Are there any typical pitfalls writers make that cause their readers to feel cheated by the plot resolutions?
