Rollup instead of Webpack / Mix?

I've been fighting webpack since being first immersed in it ~ 2 years ago. I don't love it and probably never will.

Recently I've been using rollup to bundle dependency packages, and like it a lot better. It's tempting to convert the main Laravel app to use rollup, if for no better reason than only having one bundling system across app and related modules.

I couldn't spot any specific functionality I can't do with rollup. But before I invest the time switching over, is anyone aware of a reason this might not be advisable?

I am writing everything in Vue3 / ES6
