Can you give specific times in the video when it occurs? I'm not seeing anything but I could just be stupid

For the blue yourself strategy, you just gotta try it out and see if it works. I do think rMC is prolly better but if you feel dBB has potential then go for it.

Do you have a video of yourself doing it? It would be easier to figure out where you are going wrong.

I also recommend asking this in the mk8dx speedrun discord

you got a really early trick and you landed on the small ramp on the platform that made you bounce, nothing crazy

I think in the standard speedrun, 2P doesn't really offer much. I think it lacks that teamwork aspect that makes most 2P speedruns interesting.

I can maybe see it working in a shine thief category extension, where one player takes the shine and the other player defends.
