Is there a way to go from a KProperty1<T, R> to a KProperty0<R> when I have the receiver object (T)? I.e., can I "bind" a receiver to a property?

Unfortunately, no

A bit hacky, but maybe it works for you:

class Demo(val a: Int)

fun <T, R> KProperty1<T, R>.bind(receiver: T): KProperty0<R> {
    return object : KProperty0<R>, KProperty<R> by this {
        override val getter: KProperty0.Getter<R> =
            object : KProperty0.Getter<R>, KProperty.Getter<R> by [e-mail],
                    () -> R by { [e-mail](receiver) } {
            }

        override fun get(): R = [e-mail](receiver)
        override fun getDelegate(): Any? = [e-mail](receiver)
        override fun invoke(): R = [e-mail](receiver)
    }
}

object BindSample {
    @JvmStatic
    fun main(args: Array<String>) {
        val demo = Demo(10)
        val res = Demo::a.bind(demo)
        println(res.get())
    }
}
