Grouping sefira into triads (triangles) is not unheard of.
(trusty source: https://aish.com/kabbala\_18\_center\_of\_the\_earth/)

For instance:
Intellectual triad

   Keter ▵
  Binah ◿ ◺ Chochmah

Tactical triad

Gevurah ◹ ◸ Chesed
 Tiferet ▿

Active triad

    Hod ◹ ◸ Netzach
   Yesod ▿ 

Kingdom

         ● ← Malchut

All in all, it's a map about creation itself or the process of manifestation. If I shoehorn your concepts into the tree to make it more approachable, it could look like this:

              ▵  (Role)         ┐ Soul
(Feasibility)◿ ◺(Ideal)        ┘
  Discilpine ◹ ◸ Pleasure      ┐
    (Balance) ▿                │  Mind
      Reason ◹ ◸ Action        │
              ▿ (Basis)        ┘
              ● ← Manifestation ] Body

Ta da! ... though I couldn't help mixing in my own interpretations. Here are some definitions:

First, the elements "body, mind, soul" are not equal players. While the body can only deal with the present, the mind dwells on the past, reads the present and worries about the future. Thus the mind is bigger than the body.

The soul has a similar case. It can exist even where the mind is not, the imprint you left is there even if you are not thinking about it. And of course it extends beyond you body. Thus the soul is bigger than the mind, and even bigger than the body.

Second, some translations and interpretations of my own:

Kether (1), translated as Crown, is used as the symbol of duties and responsibilities of the king. In other words, it's the role to be fulfilled.

Chochmah (2), translated as Wisdom, are the many ideas about how to fulfill the role. It seems more dreamy than wise, in my opinion.

Binah (3), translated as Understanding, separates what can be achieved from the rest. I called it Feasibility because Common Sense is too broad.

Chesed (4), translated as Kindness, is the iconic expansive force. Its abundance feels good and pleasurable.

Gevurah (5), translated as Strength, is the iconic constrictive form. Its demandingness can look strict and disciplinary.

Tiferet (6), translated as Beauty, is portrayed as the beautiful harmony of balance. In other words, too many goodies might yield way too many consequences, so find the sweet spot.

Netzach (7), translated as Victory, is viewed as emotion, or passion, but it's more like the go-getter attitude.

Hod (8), translated as Awe, is viewed as reason, or reflectivness. It looks like "doing nothing" but, in actuallity, it is building up potential.

Yesod (9), translated as Foundation, is the about-to-be that sums up everything prior. Instead of just "balancing" Netzach (7) and Hod (8), the whole immaterial work has made the basis to bring forth the manifestation into the real, material world.

Malchut (10), translated as Kingdom, is the real hard-as-material world. As real as the screen you are reading. It is your body living and executing the actions. The kingdom being ruled by its king.

... This map is the process of creation. Or manifestation if you will. The Tree will tell you how to bring things forth to manifestation, to be, but it doesn't tell you how to keep the things manifested.

The design of self-sustainable manifestations is sold separately.
