I would suggest using 1/2 it at all possible as well... but...
a curved front is actually quite a bit stronger than a large flat panel. The greater the curvature, the greater the strength benefit. Think about it, it's already bowed into a partial circle, so additional pressure will tend to put the acrylic in tension, rather than bending.
Please keep us updated if you do indeed decided to DIY the curve. I have never actually made a curved front panel like that, although I've considered trying.
