No, d1 to DP is dangerous because the opponent has to respect the DP, so when they start to block, you get d1, body press. And when they start trying to jump out of that, you can hit confirm d1 and then get b23 frame trap. Not just talking theory here, I do this all the time and it's hard to deal with if you can actually get into max d1 range.
Also, I was in the lab and figured out that d1 stuffs wakeups. The timing is very difficult but I set Aquaman to do Trident Scoop and Trident Rush on wakeup, and with the right timing, I was able to stuff both of them with d1. The timing feels like maybe a 2-3 frame window.
