I went in expecting to hate the show because the Iron Survivor concept seemed a little convoluted (and this is coming from a guy who actually liked the Championship scramble matches back in the day) but both matches delivered and the show was really solid.
I don't think Waller and Bron should ever be turned even when they're called up, just make them the moral anchors of your show on the opposite ends of the heel/face spectrum and everyone else can fit in between. They're both born for these roles. Bron looks like America don't know how else to describe him.
It's a shame Alba Fyre is so bland though because she's definitely ready for a call-up ring wise, Isla Dawn has a long and fulfilling career in BDSM porn waiting should she ever decide to leave wrestling too.
