According to this article: https://www.ericsson.com/assets/local/publications/white-papers/wp-bluetooth-mesh-c3.pdf
There are no limitations, as it only requires a firmware upgrade to work as a BLE mesh node. The hardware requirements for BLE v4.x and v5.0 are the same as for BLE Mesh.
If you can describe or list the requirements of each device/role more clearly than the BLE spec, it would help, but otherwise reading the spec seems to indicate that most if not all of the BLE mesh requirements are software implementations running on the chip, and not the hardware itself.
thank you for your answer. I have that pdf open, along with many others on my browser as I type. Now I just need to read it. I'm still in the early development phase so I'm still learning. Thanks again.

We do not have Mesh support for PSoC4-BLE. Devices that support BLE mesh - CYW20706 (upcoming releases of WICED) and CYW20719. There are also non broad-market device CYW20735 but you will have to contact the sales office with your project details and quantity details.
