Referencing appender in another appender in logback

I'm creating a custom logback appender which needs to fall back to another appender in certain situations (typically a failure). What I'm trying to achieve is this :

<configuration>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%d{HH:mm:ss.SSS} - %msg%n</Pattern>
        </layout>
    </appender>
    <appender name="MYAPPENDER" class="my.appender.class">
        <appender-ref ref="CONSOLE" />
    </appender>
    <root level="trace">
        <appender-ref ref="MYAPPENDER" />
    </root>
</configuration>

Now, I've implemented AppenderAttachable in MYAPPENDER and it does seem to work, - the frameworks sets a reference to CONSOLE appender during initialization and I use it all right.

Is it a standard way to go about the case? Is there an alternative to this approach? Ideas?

Yes, support for AppenderAttachable is likely to be preserved in the future.

Have you printed logback's internal status messages? What does StatusManager say?

Update: After the changes made to the question my answer no longer makes any sense. I am leaving it nonetheless because as an investigation tool about logback, logback's internal status messages can be very helpful.
