Doubtful but...

I dunno. I brought my Bohemian set in, with both magnum and support shot boost active, but inside the RP, the points on my clothes were different, to the point where I had neither of my bonuses

That's because Bohemian set isn't fixed with bonuses. Colin plate is and dam, kinda sucks e-e

If a non-fixed set wouldn't work, I doubt even a fixed set would. They're applied the same way.
