If money were no object that's not the engine I'd be playing with. The 6 cylinder 1HD-FTE is a real landcruiser engine. The V8 is 2 car engines (euro 2.2D avensis) sharing a crank. I haven't heard any other modern engine having oil consumption issues.
Tuning wise, VW engine tuning is essentially laid open by the companies selling tuning software (all maps identified etc). The Toyota ECU's however can't be tuned. Last I heard (~2 years ago) The editing protection in them hasn't been cracked. Tuning is essentially limited to plug in boxes to modify signals and increase fuel pressure.
You might be able to modify a duramax or similar tunable commonrail ECU to work on the engine. But it would be a horrendous amount of work.
