I have been testing a design that uses a support plate also (I have had requests for vats with an acrylic support under the FEP). One of the problems I saw was the FEP film would tend to stick to the acrylic support plate which does not allow the FEP film to bulge slightly upwards when the build plate lifts between exposures (the FEP films ability to lift creates peeling edges anywhere the print touches the FEP film, this makes the peel much easier). I am testing a vented support that allows a bit of air in under the FEP when needed. The FEP is still under tension but not as tight as the drumhead vats.
BTW this is a two piece vat there is no separate riser plate.
I am still sorting out some design issues and testing vats so it will still be a month or so before a vat with an acrylic support sees the light of day over at flexvat.com

I have constructed a frame directly in the opening of the LittleRP fits and as a glass layer I use an acrylic glass XT with a high UV light permeability.
The advantage in this solution is:
1. The build plate lies 100% flat
2. The distance to the projector is reduced
3. The foil of the FlexVats must not be stretched any more so tightly, because it lies on the acrylic glass.
4. you do not need any longer the bottom Frame of the Vat who tight the foil.
Am curious on your opinion
