Brewing gluten free on same system as regular

[Covert Operator]

I'm looking at a few recipes for gluten free beers to roll out (understanding it will most likely have very small demand). What is the collected wisdom as to how much of my existing system can be used for both regular craft beer, and gluten free.

I understand sanitation must be top-notch, and the big fear is cross contamination.

Must I have a separate dedicated mill and hot side for gluten-free?
