Hypocritical Greed & Nasty Ideologues

I'm slowly starting to understand What A Carve Up more and more as I look further into the book.  I'm starting to understand the Winshaw family and their values as they display levels of greed. I feel this theme of greed could work in my favour when designing this book cover as I can generalise the characters without focusing too much on a particular character within the book.

This is a quick idea I had which shows a dial with a list of words that I find display the Winshaw family and as in the novel each of the family members meet their doom through their profession. This doesn't give away much other than the possibility of death within the story.
