While I don't know how easily, I would guess with some fiddling you can make a transition piece and get it to work such as suggested above. I have to say in my own experimentation with O-gauge track this was mostly a waste of time. However it took me a while and a lot fiddling to reach that conclusion. I then sold off all of the one track I didn't like. But maybe HO is a little more forgiving. The Lionel fastrack I had with O was something I adored until one day the noise got to me and I couldn't stand it. Eventually that's the one I sold off. But the new magnetic lock version seems pretty clever. I wonder also if its a bit quieter. The bachmann HO track which I have some of is hollow. At first it did not seem that noisy to me but then I got some plain or traditional rail/tie track. Putting these two together on the same line reveled a solid 10 point drop on a DB meter I borrowed -- very noticeable. Still I like the solid feel, the pre-made form and so forth of that plastic base track...
