I don't understand what you're trying to do here. You have a product with several attribute options, each with a different price, but you don't want the customer to be able to choose which one to add to the cart? You just want to display the options and price? Then how can you possibly sell those different products from you site? The only way I can imagine this would be necessary is if you just want a catalog where no purchases are allowed. In that case, overriding a theme function or the product template to just display the pricing would be my first approach. I don't see that changing Ubercart to add non-selectable attribute options would be useful or necessary.
