No, it’s unfortunately not possible to do something like this – the CLR doesn’t provide any efficient way of doing that kind of type test. See How to cast an object to a list of generic type in F# and F# and pattern matching on generics in a non-generic method implementing an interface for a few (rather ugly) solutions.
