Those cap blocks crumble pretty easily. They are porous just like cinder blocks.
They adsorb a lot of moisture and will freeze and crumble and break.
They have little strength and can be broke with modest impact or pressures.
Someone may make concrete blocks however.
Depending on the part of the Country you are in you may be able to get thick slabs of stone from a quarry. I say that on my Uncle in the fifties using that for a walkway and patio. They were six inches or so thick and very heavy, of course.
A firm base down at least to frost line and top six inches of the new mix that is rock and concrete dust or dry concrete leveled and tamped down you can put just about any pavers including paving brick on it and remove broken ones over time if any develop.
