How about making a raised earthen container and just using pond liner?
This is how I'm doing my next filter.

Sounds interesting! I have an above ground retaining wall stone with
liner I plan to use for plant filter, or veggie-filter, but I don't
have as good an experience as others with plants for filtering. The
bottom of such tanks always collect mulm. What filtering
devices/media do you plan to use in such a tank?
