Meanwhile, no forcey-Renegade is a stylistic issue. There's no real thematic gap for a Renegade there (nor was there any significant demand).
Qui-Gon gave us the Ronin. If Yoda had been a Renegade it might be different.
You have to move away from the idea of 'Renegade version of...' and leaving at that. That is 100% what I was trying to get away from- creating templates just because they could be imagined in a rules-mechanic sense. The Ronin is 'Jedi without a Master' and the Freelancer is 'Jedi Mercenary', and I can tie them together with the same social penalty, but beyond that the themes run dry. We only think about there being equivalents of each type as that is how I had set it up before.
You can conceive of 'Jedi who wanted to go and study stuff away from the Council', but where the theme fails is them taking up a lightsabre and going out and fighting things. Scholars are part of a police force, but Renegades need to be self-motivated to get into these insanely dangerous stories and their desire for action is what covers it. So whilst that template would have a broader skill set, it would have fewer force powers, fewer fighting powers, and wouldn't really be interested in getting involved in the plotline. I was really bending to create the backstories for Wanderer and Seeker and was never happy with them.
(This is also why we don't see where Ascar learned from- because it would be, fundamentally, extremely dull.)
That being so, having Renegades not as a mirroring of the Jedi structure but instead as a way of creating distinctive Light Side characters- in the way the Brute and Corsair are distinct Dark Side ones- works much better, thematically.
