Would using this gravel as paver base be detrimental to the paver’s stability? : HomeImprovement

We are in the process of installing a greenhouse in our back yard. I’ve been digging up the top soil and sifting it through 1/4″ hardware cloth to separate out the dirt and rocks. I’ve already collected about 1 cubic yard of rock with an average size between 1/4″-3/4″ – though some are bigger. Here is a picture of the gravel

My plan was to dig down ~9″, fill with 6″ gravel, 1.5-2″ sand and the remaining height with pavers. I plan on renting a compactor as well. I estimate that I’ll need ~4 cubic yards of gravel & 22 cubic feet of sand. Given that I’ll need about 4 cubic yards of gravel, I’ll still probably need to buy at least 1-2 cubic yard to get the 6″ height I need.

Do you think it would be detrimental to the stability of the pavers if I used the gravel I’ve collected as the paver base (keeping in mind I will likely still need to add 1-2 cubic yards of new gravel)? It just seems like a waste of money to have to pay to dispose of the gravel I’ve collected just to buy more gravel.

Also, it should be noted that the greenhouse itself will be supported by concrete piers and the weight will not be on the pavers.

Thanks for the help.
