Doing an easy tasty tonkotsu ?

I used to use this pack (second photo) to do my ramens at home. Now I mostly use Jin ramen packs and mix it with korean soup base (third photo)

The thing is that now the tonkotsu concentrate feel verry weak. It was already compared to one made from a good ramen shop.

For the bowl in photo I mixed the concentrate with homemade chicken bone soup. But again taste is weak.

Do you think it is possible to do a tasty bowl without making a 12h tonkotsu ? Any tips ?🤔
