convert zigbee to digimesh-XBeePro ZB S2C

I had been advised to purchase the…XBP24CZ7SIT-004
Desc.: Zigbee / 802.15.4 Modules XBee-PRO ZB S2C TH for my application.
After personal investigation and watching some of the DIGI videos, it has become apparent that I possibly would have been better with the DIGIMESH version.
Is it possible (and how do I do it) to convert these modules to DIGIMESH protocol.
My intent is to utilise the MODBUS protocol to control 2xAuduinos remotely.

No, the S2C does not offer a Digi Mesh firmware at this time.
