Enhancement - Adding strongly typed RttiVariant from Delphi to expose to DWS script

I'd like to get some compile time checking on my scripts so exposing my global 
variables as just RTTIVariant is not desirable. I'm exposing the Screen object 
to script using the following code.

Delphi side global variable creation

var CompVar : TdwsGlobal;
..
CompVar := dwsUnit1.Variables.Add;
CompVar.Name := 'Screen';
CompVar.DataType := 'RttiVariant';
CompVar.OnReadVar := onGetScreen;

procedure onGetScreen(info: TProgramInfo; var value: Variant);
begin
  value := TdwsRTTIVariant.FromObject(Screen);
end;

What I would like to do is replace 'RttiVariant' with 
'RttiVariant<Vcl.Forms.TScreen>'. Script is not happy with strong RTTIVariant 
types being used on the Delphi side but it is happy on the scripting side.
