I don't understand why you are contemplating changing the whole rig! Why not try a different cartridge first to move the sonic signature in the direction you're seeking (assuming that your phono stage is up to the task).
One of the Zyx range (R100 or higher) would be the easy option - they are fashionable currently - so you could try one out and if it's not to your liking you could sell it on without losing too much.
