I used the 'plot to overthrow the Chancellor' scene in v3, so yes. It lets us see that Obi-Wan is in the know and involved with this stuff, giving a little more weight to his later dialogue about the Chancellor being evil and getting defensive about the idea of taking over the Republic as Anakin sees it.

The other scene you mention needs some FX wizardry, and would require careful editing of later scenes between Palpaying and Anakin, so I never really thought about using it. Upon reviewing it, it seems very unfinished and "on-set," with poor line deliveries. I think they did well to cut it and spread its pieces across other scenes.

Thanks for the question!
