You know, there've been lots of sports with mixed pair competitions, but NEVER anything even close to this.
Did you 2 think of specifically mentioning/pushing that angle? Even the producers may not have considered this.
Every episode thus far, has featured at least 1 female competitor, so they're obviously actively looking for female competitors, but if they haven't considered it for next season, try planting that seed: male + female duos competing as a team. Relay chops, tandem chops.
You want more adrenaline? Set up 2 courses side-by-side. Each team member has to chop half, before the 2nd team member chops the 2nd half. Teams go head to head in elimination. Last 2 teams standing per episode, compete in the more difficult course, for the chance to compete in the Finale.
They can make it even more fun, by mixing power vs timing/finesse obstacles in each portion, while allowing the mixed pairs to decide who does the 1st vs 2nd half (so there's a possibility of the guy in 1 team going head-to-head with the gal from the other team, before handing over).
They're already going for speed with timed competitions, but head-to-head is always more exciting with the possibility of leads swapping (if their insurance underwriters would allow a head-to-head format).
Just a thought
Would be awesome if you 2 can convince them to have you compete
