That is probably the easiest path to the 6th seed. However, in spite of the Texans sending season ticket holders an email that they don't need to pay for playoff tickets the Texans could make the 5th seed and host the AFC Championship game (will people who listened to them lose their PSLs????)
Week 16: Texans beat Ravens, Chiefs beat Steelers, Panthers beat Browns, Vikings beat Dolphins, 49ers beat Chargers, and Raiders beat Bills. 9-6: Steelers, Ravens, Chiefs. 8-7: Texans, Bills, Chargers. Out at 7-8: Dolphins, Browns.
Week 17: Texans beat Jags, Browns beat Ravens, Bengals beat Steelers, Chargers beat Chiefs, and just in case the Bills did not lose to the Raiders - Pats beat Bills. 9-7: Texans, Steelers, Ravens, Chiefs, Chargers, maybe Bills. It will come to the conference record tiebreaker: Texans have the best conference record of any of these teams (thanks Titans and Jags!) and get the 5th seed. Then simply win 2 playoff games on the road while the 6th seed does the same - and BAM! AFC Championship at home!
