Can rotoscoping work on text that has 3D tracker applied?

Is it possible to rotoscope some text that has 3D tracker effect applied to it?
If not what is the best way to mask this text to give it the illusion that it is going through the door.

Seeing as the 3D tracker has created a 3d virtual space for you, you can simply place the text in 3D space and it will remain. And you can also create a 3D solid to act as a matte for the door.  You'll need to switch to the Basic 3D renderer for track mattes to work (or precompose the door and a duplicate of the camera and separately a camera and text, then use the Set Matte effect).

I should have also added that you can roto the door, if you prefer.  The footage remains 2D video, it's just that there is a camera in 3D space.  So if you don't get on with what are nicknamed 2.5D layers, roto is still an option, but you'd probably have to split the roto-ed layer to make it look like the text passed through the door.
