It would be possible to re-sync, but if you were more than one cycle out of sync, it would take more than one field to re-establish precise sync.It depends on the application. If you are done doing your video-related work very early in the field, you could reacquire on the bottom of thefield.
And of course if you just want to mix two modes in a nonstandard way, you can leave a few screen lines of black between your graphics and text (or between your lo-res and your hi-res, or whatever). Then you wouldn't care where exactly in that range the switch happens (as the pixels on both sides of the exact switch point will be black), so no cycle-exact lock is needed.
