One possible solution - If you assemble the AndyMark shifters, play with them a bit, and after kickoff you alter them somehow (something as simple as drilling a hole somewhere), according to past years' rules you've got yourself a newly fabricated mechanism, which historically has been legal to use.
To echo what has been said by Mr. Lavery dozens of times, rules from past years' competitions do NOT necessarily carry over into future games.
Good luck with your rookie season - sounds like you're already off to a great start.
