Flex build plate with magnets

After seeing this video:

Is was wondering. Does the Form buildplate allow for such a thing. I could easily manufacture a small flexible sheet drill an array of holes and put some magnets in. This would only offset the buildplate by 0.3mm. Can this offset be accounted for in the printer. AND if possible can we print directly on the buildplate without the worry of the first compressed layers. This would make it so much easier for flat objects.

You can increase the Z-offset in the Form 2. Or just machine a bit off the build plate. There is a few millimeter of aluminium.
