Improved roll center

I have an e-body with all stock e-body suspensions pieces. I want to improve the front roll center. Rules call for stock UCA's. I'm running 1/4 mile pavement. Unlike my normal method, I want to get opinions before I buy a bunch of parts.

Will adding longer ball joints get me where I need to be with e-body spindles?

C-body spindles are an option. I prefer to the run the 1973's. It looks like you can use the e-body lower ball joints with slight modification. Having are hard time finding a pair of 73's.

Are C-body spindles and the longer ball joints the way to go or is that overkill?

Thanks for your comments.
