Reunion portrait lighting advice

Another photographer and I are going to be taking couple and single portraits at a 25th HS reunion party. A third photographer will be taking candids. The most likely couples pose will be one sitting one standing, waist up. There will be about 250 guests and two portrait stations. For mine I’m thinking two studio strobes 1:1 with 46”ish silver umbrellas either side of the camera to avoid one person shadowing another, plus a background light. Maybe a speedlight as a hair light.

To me the lighting setup doesn’t seem very interesting but I don’t want to have to do any wrinkle or shadow retouching – just crop and batch exposure if needed. I have a 28” Westcott Apollo softbox that will fit a small studio strobe but that doesn’t seem to belong. Anyone have advice?

I would keep the setup as simple as possible with the least adjustment needed between couples. I would not use a hairlight because that might very likely have to be adjusted between couples because of their different heights.
