Oh god it sounds about as crap as Catherine Tate's ill-fated Queen of Oz. And Tate is talented.
It's hard to satirise or dramatise the bizarreness of the Royal Family successfully in any original, watchable way precisely because it is so bizarre. Most productions end up full of tedious expositional dialogue and anachronistic props, looking utterly derivative of one of the many, many previous efforts. For every Spitting Image sketch and fictionalised episode of The Crown, there are dozens of flops. There are also hundreds if not thousands free videos on You Tube and similar platforms. It's a very crowded market.
And let's face it, Omid Scobie is no Armando Iannucci or Hilary Mantel. I suspect his little axe to grind may be rather mangled and lame. All the 'bombshells' against the royal family since 2020 have already been diluted with time and are, by and large, disbelieved.
(Incidentally, as well as being a writing genius, Armando Iannucci is Patron of Child Poverty Action Group and actually does stuff for it.)
