Is there a way to change front/back properties in a Flipable?

[Beriol]

The Flipable element can easily offer nice transitions. But is there a way to change the back and/or front once they're set?

For example, if I do this:

@
Flipable {
id: flipable
front: Image { source: "someImage.jpg" }
back: Image { source: "anotherImage.jpg" }

Image {
    id: img
    source: "yetAnotherImage"
}

Component.onCompleted: flipable.front = img
}
@

It gives me this error:

QML Flipable: front is a write-once property

So, are there any workarounds to this? I tried a few things, but couldn't come up with a solution.
By the way, why is there even there this limitation?

Change the source of the image, not the object. Or use a Loader.

Well, yesterday I tried something like that (not with an Image), but it gave me an error saying that I couldn't modify read-only properties; I figured since the front/back were write-only, they're children properties were read-only. Now I just tried changing the source of the Image and it worked just fine. I don't know what I was doing wrong yesterday.

But the Image was just an example. What I really need is a way to change insert a view created and istantiated from C++ into the front/back properties.

I was messing with the the Loader a few moments ago, and it might look the thing I need, except that I can't load the new view created from C++ with that because the component is actually instantiated in the C++ side...
