Sadly - for you, anyway - unless you decided to abandon Lizzy and Darcy in, I don't know, Kamchatka for the duration, you're working with a toolbox that we're all pretty familiar with. Ash, delightful boy that he is, can't carry all the weight of surprise in the Lizzy/Darcy story. I find it rather fun to see what you're doing with familiar plot elements, though I can see where it would be frustrating for you.
As for Lady C, I just read the end of the book yesterday and wrote a scene involving her last week, so she and her objections were on my mind. ;)
