Physical Probing First Layer

Question: Does the Duet Wifi have the ability to receive on any of its inputs RS232. If so what would be involved in interpreting messages?
The reason for asking is that I have been watch videos of the BambuLabs X1. This has a micro lidar for calibration. But I understand it has problems with some bed surfaces, namely reflection or textures. I would have thought the textures though could be resolved by averaging.
I have a tool changing machine and I thought I could put in place of one of the nozzle tools a Digital Dial Indicator (and perhaps other scanning sensors). e.g. https://www.ebay.co.uk/itm/364668106198
The rational is that we may have very sophisticated ways of sensing nozzle height above bed but its really the physical layer height that is important as extruded. Perhaps a Dial indicator would solve the bed texture and reflection problem.
Really this is no different to a CNC machine where it measures the parts during machining.
Welcome opinions.
