That wouldn't work (you'll get an exception). You need to define "new" instead:
class RubyClass < ClrClass
def self.new (param1)
super
end
end
CLR and Ruby use different allocation schema. CLR creates objects atomically
while Ruby creates an empty/uninitialized object and then calls initialize. You
can't use Ruby's way on CLR objects that don't allow empty object allocation
(don't have default constructors).

I may be missing other context, but what happens if I want to do this:
public class ClrClass
{
public ClrClass(string param1) { ... }
// no other constructors
}
class RubyClass < ClrClass
def initialize(param1)
super(param1) # or just super should also pass the param1 if my memory is
correct...
end
end
