There has been discussion on this elsewhere. I think in LN, lama practice is emphasized with outer, inner, secret and most secret versions. Generally, as far as I know, Palchen Dupa is the common LN yidam, or any associated practice (Hayagriva, Vajrakilaya, Shinje or Yangdak.) Dakini practice (Dechen Gyalmo) is only undertaken as a main practice after completing the yidam, just as yidam practice is undertaken after finishing inner lama (Rigdzin Dupa.)
Also, and this was what was mainly discussed elsewhere, the secret lama Chenrezig practice is often given in place of Palchen Dupa when giving three roots empowerment. Why? I'm not sure. Easier to give perhaps?
I don't think there is the commitment to do three separate three roots practices daily, as maybe in other terma traditions, but I could be wrong on that.
I'm not sure if Medicine Buddha or things like that fit into any LN schema unless you want to do them, of course.
There are general guidelines and a tradition of doing things in a certain way, but essentially, as ever, if your lama tells you to do something else, you do that.
