Who might the other two SMCs that most wanderers on Earth incarnate from be?

Here's the L/L channeling that states Q'uo is a combination of Ra, Latwii, and Hatonn:

Group question: Our question this evening has to do with how extraterrestrial contacts with human beings on planet Earth in third density may or may not infringe upon the free will of the entities contacted. We are wondering about the philosophy that the extraterrestrial entities use in order to decide whether or not to make contact and what kind of contact to make.
For example, during the Manhattan Project, information from positive extraterrestrial sources was given concerning nuclear energy that’s very specific. There have been other contacts, such as Billy Meier’s contact and the contact with Phyllis Schlemmer from the “Nine” and Tom, which have had more or less specific information to give. We are wondering if this infringes on the free will of the humans who are contacted and what exactly is the philosophy of the extraterrestrials when they make contact with regard to specific information and the infringement on free will.

(Carla channeling)
We are known to you as the principle of Q’uo. Greetings, my friends, in the love and the light of the one infinite Creator. It is our privilege and our pleasure to be with you this evening, to share in your vibrations and to respond to your query concerning the infringement of free will by those of extraterrestrial origin who have been speaking to your people and in some cases meeting them face to face.
As always, before we share our thoughts, we would ask each of you to be responsible for your own judgment and discrimination as regards the things that we say. If our thoughts have resonance for you, then by all means follow the path of that resonance. That is why we are here and we are very happy that we can give you food for thought.
If, however, we miss the mark and do not interest you particularly in what we have to say, we would ask that you leave behind our words and keep moving until you find that information and that inspiration that does resonate with you.
We thank you for this kindness, for it enables us to speak freely without being concerned that we will infringe upon your free will.
You asked this evening concerning the nature of contact betwixt extraterrestrial entities and Earth entities. You asked about free will and how extraterrestrial entities feel about the free will of those upon planet Earth.
We may start with ourselves. We of the Confederation of Planets in Service to the One Infinite Creator have, shall we say, experimented with contact, in terms of face-to-face contact, in your far distant past. We found that the direct communication face-to-face was neither positive nor negative, but only that which the entities of that time felt was part of the natural universe, which at that time was replete with many gods and many unusual things.
What caused us to become more and more aware of the difficulties of clean communication with those of planet Earth was the inability of even the most powerful entity to maintain the purity of the initial contact, once the information we gave had resulted in the pyramids that were built. Instead of the pyramids being used for the purpose for which they were built, they became used for the purpose of the few, the elite, the powerful, and the wealthy.
We became aware of the impossibility of blending physical presence with a lack of distortion. We, those of the Ra group, those of the Hatonn group and those of the Latwii group, chose not to use again any means except the channeling through instruments such as this one as a way of communication of concepts hopefully helpful to the spiritual evolution of those on planet Earth to the population at large.
We are not the only entities from elsewhere which are interested in planet Earth at this time. There are many entities interested in your planet that come from elsewhere. Some of these entities are of the Confederation and have agreed with those of us who have had a relationship with those on planet Earth previously, so that in the interest of retaining positive polarity we have chosen not to appear to your people.
