I wouldn't.
I mean - its a great ride. Nothing beats going super fast. But here's my issue:
It cuts the park in half. ...And especially with the TOTII tunnel, it's not appealing to look at
It's noisy AF. It completely destroys the park atmosphere
Its unreliable. Constantly down for maintenance, but even when its up, you can't guarantee it'll be up all day
Its expensive. Each launch chews up SO much power to drive the car.
Its capacity is shit. 14 people, 30 second ride, 60+ second load time (if the staff are on their game) for 560pph max (and let's face it, it almost never goes that frequently)
It's old. The ride operated for 13.5 years before it was converted to ToTII. In it's second incarnation, it's about to hit a further 9 years. It's a 22.5 year old ride, and while groundbreaking (and record breaking) in 1997, technology has overtaken it - When SFMM upgraded to S:EFK a month after TOT, a new, modern, more efficient launch control system was installed. Dreamworld passed on the upgrade, and still operates with 1997 controls.
It's slow. For whatever reason (but rumored to be cost-cutting) the record breaking launch of 100mph is almost never reached today - the ride operates at a lower power, and never uses the top 30% of the tower, as it did in it's heyday.
These days, the only real reason for keeping it, especially with all of the currently present reliability issues, is sentimentality. And there's really no evidence that Dreamworld is sentimental - just take a look at the cinema steam train marketplace wipeout paddlesteamer traditional disney-esque main street facades... oh fuck it - they aren't sentimental.
