Pour permeable concrete between pavers

Hi, I have a small back yard which consists of pavers and stones. The stones need to go as we have kids and its just hopeless. I want to keep the pavers if possible and replace the stones with permeable / previous concrete. The area is small, no more than 3 x 3 m (see photo). We can remove the stones in preparation and there is gravel Job to be completed asap within next two weeks please.
