Funny that the Hivers freaked out over unrealistic rumors that Steem would be turned into a Tron token and here you are doing the exact opposite. I like it, it's a good method of adding value to Steem while doing very minimal development work on the Steem side.
I think you're going to end up with a lot of frozen TRX with the key-burning policy, though. Historically people here don't hold onto their keys as well as you might be used to on other chains. Maybe a lot of those went elsewhere but I think you still will end up with a lot of people here as their first crypto. Might be a good idea to have some sort of recovery system.
