No.
Plain & simple. Out of respect for the cm's at CRT, and you wanting to check in on time, and eat quicker, I wouldn't.
You'd have to be at the VERY front of the "line" plus then there's all the people who were already back at the BBB or had a pre park ADR that are done now, plus fast passes. You have to wait in the line, THEN have interactions with them and then get around to CRT, it's not worth it.
The rope drop show may start before 9:00am, but the park doesn't actually open til 9:00, and with the new procedure of "walking with a rope" thanks to the A & E dash, it wouldn't be advisable.
