I did a thought experiment like this, attempting to see how the Arts could transition into the Arcana from Mage the Awakening.
Advances led to the uniting of Animal, Corpus, and Herbam under Vitam (Life). Aquam, Auram, and Terram united under Materiam (Matter). Imaginem and Ignem were joined under Vires (Forces). The Limit of Time and the Limit of Aging were overcome which led to the Form of Tempus (Time). Breakthroughs dissolved the Limit of the Soul which added the Form of Mortem (Death). The Form of Spatium (Space, or Correspondence in the old Mage system) came about after the Limit of Arcane Connections was removed from Hermetic theory. The Form of Vim was expanded and became Aetherem (Prime). Note that this Aetherem is not the same as the Form of Aether included in Dies Irae. The Form of Mentem remains the same (Mind) but a new Form of Spiritum (Spirit) is invented as a breakaway when the relationship between Mentem and Vim is explored. The Form of Fatum (Fate) is also developed from non-Hermetic magic (Faerie magic and other forms of magic).
This gives us the ten Arcana from Mage the Awakening and this is what the Hermetic system could look like in the 21st century.
You can also map the Practices to Techniques, but this is probably unnecessary because each Technique encompasses more than each individual Practice.
