Combine groovy and kotlin

I have a project compiled with gradle using a lot of groovy. Right now I have no time to migrate all of that stuff to kotlin. Something I’ve migrated already - things that were written as plugins, but there are a lot of stuff left in groovy.
I want to add some new tasks to the project and I want to write them in kotlin.
Is it possible to use kotlin dsl without making plugins?
Just include kotlin build scripts into groovy-based project or something like that.
