Combine two feat. into one

How do I combine two feat. into one?

Example-Steve Aoki-Turbulence (Promo Only Intro Edit) (Feat. Lil' Jon) (Feat. Laidback Luke)

Example-Steve Aoki-Turbulence (Promo Only Intro Edit) (Feat. Lil' Jon & Laidback Luke)

You could replace ) (Feat. with &

The problem is that I still will have ( and the other Feat.

Strange.
$replace('Steve Aoki-Turbulence (Promo Only Intro Edit) (Feat. Lil Jon & Laidback Luke)',') (Feat.',&)
leads to
Steve Aoki-Turbulence (Promo Only Intro Edit& Lil Jon & Laidback Luke)

I should have explained it a little better. I have multiple files like my first example. I want to run them in a batch and knock them out simultaneously.

Timbaland-All Y'all (Intro) (Clean) (Feat. Tweet & Sebastian) (Feat. Magoo)

OK - the first example has once the pattern of closing bracket-opening bracket-Feat.
The second example has that combination twice.

I used your supplied string to prove that the principle suggestion works - and that would have worked for all the files that have the named combination.

Now, with the new data, please try Convert>Tag-Tag for TITLE
Format string: $regexp(%title%,'(.*)\) \(Feat. (.*?)',$1 & $2)

Thank you, you are the best!
