I don't think this will fly. Abstract on the class name itself makes it
non-instantiable, however subclasses are not abstract and can be instantiated:

// can't be instantiated
abstract class Foo { void foo() { } }  

// is not abstract and can be instantiated
class Bar : Foo { }

Whether or not there's an abstract keyword next to the class name doesn't tell
you whether the class actually has abstract methods, so there's no benefit
forcing you to add 'abstract' to the name.
