Theoretically it is possible under the current rules to do something similar (assuming I have read and understood the JAR-FCL correctly).
Following a modular route:
- PPL
- Hour building
- ATPL Ground exams
- SEP CPL
- SEP ICAO recognised IR
- Pitch up to a 737/Airbus TRTO. Get type rated on said jet.
With this route you could potentially emerge as a 737/Airbus F/O with a type specific IR and approx 200hours.
Dunno if anyone has tried this route and if it has been succesful.
Maybe I should copyright the idea....
