Adjustable attributes

Is there anwyay without extending the whole product logic, that i can create 3 product atributes and do the following.

requirement 1) Attributes width, height and depth, min max values
requirement 2) Although customer can adjust within min max, price is effected per 100mm

Hi Steve

select p.Name as Product, a.Name as Attribute, v.Name, v.PriceAdjustment
from Product as p 
join Product_ProductAttribute_Mapping as m on p.Id = m.ProductId 
join ProductAttribute as a on m.ProductAttributeId = a.Id 
join ProductAttributeValue as v on m.id = v.ProductAttributeMappingId 
where ProductId = 24
