Four seater EW plane? Thats rather unlikely.
F117? - very interesting, but I wonder if they will get enough data on its RCS and how it changes from different angles. Without that it would be rather underwhelming to drop those 2 GBUs all the time
F-111? - For me it doesnt bring anything new to DCS and never ever would I call this brain melter.
Rafale - Its a bit older than Typhoon, around the same age as our current F16 and F18, but Razbam would be expected to get that license first since they cooperate with AdA. Certainly face melting and something new (especially if it would come with Charles de Gaulle)
