Improvement of the site functionality on OpenCart

There's a website on the OpenCart platform. In this case, the unloading of goods is made through the file *xls, formed from the database 1C version 7. (in unloading there are the following fields: Category - the way where the goods are laid out; Name of the goods; Article of the goods; Size of the goods; Color of the goods (written in words); Description (not already used); Units of measurement (staff, meters, packaging, etc.); Price of the goods; Quantity of the goods; Code of the product (code of the product), one image is loaded from this site); Uploading can be changed as it will be necessary for the correct operation of the site (there is a programmer 1C).

The task is to change the presentation of goods in the category and directly the Product Card.

Namely. In the category, display what is in this product with this color article. For example, a button with the article 1044 should display two colors (gold + black and gold + white).
Example: Text hidden

As for the product card, it is necessary to present the cubes in the form of colors (while choosing one or more color cubes, a list of the corresponding goods is displayed)

After all these works should not suffer the existing functionality, i.e. Work basket, filter, search, etc.
I am also interested in the price and the price of the issue. If you can not implement this functionality on OpenCart are ready to consider the transfer of the site to another platform.
