I’m not sure I’m following the order of scenes you have in mind. If the fireplace scene is to be retained, it would be best to leave the original transition into and out of it.
TAS basically replaces the original kiss by the lake scene with the Padme’s family deleted scene, then uses the kiss later to replace the fireplace scene.
What order of scenes do you want to have? Let me know and I can try to make that happen, but it can be rather tricky to get a decent audio transition and sometimes that limits what I feel good about.
Oh, maybe now I understand what you mean. Basically, your problem is that if you add the scene in front of the fireplace, then there is one scene you don’t know where to put, and therefore the order of the scenes and the jumps between Kamino and Naboo get messy. Did I get it right?
Well, if that’s the problem, then you could turn the scene where Anakin levitates the pear and the kiss scene into a single scene. That is, when the scene where Anakin levitates the pear ends, you insert a transition and go straight to their kiss on the lake, without jumping on Kamino first. In this way, despite being two different scenes, it turns out like if they’re one scene and therefore you can add the scene in front of the fireplace without any problems. Then, after the kiss, you jump on Kamino, and then you return on Naboo with the fireplace scene.
So, the order of the scenes would turn like this:
Arrival on Naboo;
Padmé’s family scene;
Scene on the grass;
Pear levitation scene/Kiss scene;
Fireplace scene.
