If I'm reading right, sounds like you're only dissatisfied with the rearmost ledge and cup depth.
If that's the case, instead of buying another chinrest, you could try different materials on the chin rest.
Using foam, moleskin, felt, leather, or any other such material and fabric, you can fill the bowl and soften the angle of the lip. You can contour it how you like and make it as firm/soft and grippy/slick as you like. There are ready-made products on the market such as "the impressionist" and "the strad pad" for this purpose.
@Mouse This is what it sounds like you are describing for your chinrest. The Impressionist for 14.90
The little circular pad is just to keep the violin from sliding around on your shirt. Helps with control. There is a foam pad sold at fiddlershop that is contoured to fit the shoulder.This one is a Belvelin for 17.50
I don't have any other violin shops catalogs memorized but i seem to spend hours on the Fiddlershop store at a time. They have the lowest prices I have found on pretty much everything, Guarantee on their products, and the Fiddlerman lines are deceptively worth way more than you pay when compared to the price and quality of other stores.
I should put in an application. lol
