Das kann leicht gemacht werden, hier ist ein Beitrag wo das Schritt für Schritt erklärt ist: http://multimixer.gr/17/01/2011/change-the-width-of-your-oscommerce-store/
Any type of custom price calculation based on options is possible, you just need to be clear how exactly the final price is "constructed"
Example

I was gonna use that but it didn't even install correctly. have to get on to themeforest for a refund...thats why i went back to using your system - which works fine out of the box with no hassle (Well minimal stuff thats easy to deal with :) )
