This is literally how this all started for us lol. Senior wanted to try to migrate everything to Kotlin in our project. Migration never finished. Now one of our major repos is just half Kotlin half Java. Devs on our team learn Kotlin by unexpectedly encountering it when they need to touch that code.
Maybe it’s because I know both languages but is that really a big issue for people? The interop is great, and kotlin is very readable, so the cost of context switching between the two is miniscule.
Some people have an extreme aversion to learning new things though. I feel that holding yourself to the standards and limits of your lowest performers isn’t a great thing.
Just use Kotlin
