Paver driveway build, put the old concrete under the base material?

So, I have done my fair share of hardscaping. But never a driveway.
Our soil is gumbo, not the best conditions for building anything, lol. So here is my thought....and this is for my own house...
I have a 1000 sq ft concrete driveway, the concrete is shaleing pretty good, but it is still solid.
My plan...using a concrete saw, I would like to cut 6'x6' squares and stack them out of the ways. Then dig 12" down, and place the concrete squares back down, and top with 8" of base.
I am not sure if this will help with shifting or not? I know it is not common, but I really don't see a problem here...any thoughts?

How do you plan on moving these 6 feet blocks without breaking them?

I am just looking to decrease the risk of rutting. I still plan on using road base on top of the concrete. I p,an to move the concrete with forks on a skid steer.
I don't really see the need to haul all this concrete away if it can be used to strengthen the base under my new pavers. .????

If the excavated area is compacted well I would see it being a problem, unless it causes some drainage issues. Seems like more work than just getting rid if it.

So your going to move these 6x6 concrete squares twice just to make a base? Why not get rid of all the concrete and start new. Seems like it would be less work.

Sounds like a job for geotex. Is hauling the concrete a problem?

If you weren't covering it with interlock, then it would be fine, but to add granular and then interlock, I wouldn't chance it. Especially in a high clay zone you're likely going to see some frost heaving.

You would still need to have a granular base under the concrete and geo tex, so imo get it out and start from scratch. You'll sleep better at night knowing you did it right.

Wouldn't chance it also u will rut the soil when placing the squares w the ss if your soil is gumbo. You could honestly install 5" base and compact the lift by the time u install the slabs w the ss not to mention the labor and blade and pissed off neighbor it will cost u by cutting the slab and moving twice..
