Yes, I believe this can be accomplished in a number of ways. The simplest is probably to use the "Product Type" field to categorize them, which would give you the ability to use it to aggregate sales basis this classification. Better Reports has built-in reports specifically for this classification.
Alternatively, you can use a tag system which our app Better Reports can also pick up. This would require you to tag the products with their new categories and Better Reports would be able to split the sales basis this new classification.
We can also use the product metafields (if you have any).
So yes, this is indeed possible
Let me know how you go.
