then seo url should be : example.com/category_seo_name/product_seo_name_of_product_id/any_custom_keyword

please suggest some changes/modification .

Yes, it is possible. But it is required to extend the SEO module. I think, it contains all necessary hooks. So just hire someone to make additional changes
