Can patio blocks be used in building a foundation along with concrete blocks?

I'm not 100% certain exactly what you have in mind here, but pavers are not really designed for this purpose, and are a lot more expensive than cinder blocks to boot; I can't think of any reason you'd want to do this.

If you just want to hide the ugly cinder blocks, you could probably use pavers as a facade ... in this case they're not actually supporting any weight, they're just hiding the real foundation. I don't think it's a particularly clever idea, though; pavers are far thicker and heavier than you need.
