Seconded!
There are a lot of modules that would make sense like niche skills (AI Whisperer, Dance Mastery, BJJ and Grappling Mastery, Deep State, Prevent Premature Ejaculation), Auras of course (King’s Radiance or Primordial Aura solo would be a blast), the Synergys as light alternative to cores, the SPSs for focussed healing (Synergy: Preordained Vitality would probably not be as demanding as Paragon) or just the one module that works on a central topic of your life.
Adding modules into the first slot would be great! (Second slot would be great for some of the killer kombinations mentioned here: SYNERGY Module Suggestions (Official) and for the MDFYs etc.)
It could also satisfy the hunger for major niche programs. You want a standup sub? Song of Joy + Dragon Tongue with ZPQ and Thunder and you are good to go.
