Stellar coronagraph.. plans for DIY

Inspired by this work on Lyot coronagraph and Rolf Olsen's work on Beta Pictoris, I started to think about my own version of stellar coronagraph.. It may be based on Panagor slide duplicator (not used much recently, mainly collecting dust in drawer). ( I replaced original Panagor lens & holder with SMENA-8 lens, it is better). It will be used on C11 and IMX291-based web camera (or modded Canon 450D).
Sketch is attached.
