Hello there,
Well, considering that we are targeting the NVIDIA Jetson Nano, one of the most powerful development kits at the time, it would be great to have at least a camera and some sort of microphone/speaker in the kit, as the system is made to match AI applications.
So, based on what SeeedStudio already have, I’d recommend to add a MIPI-CSI Camera, like those made for Raspberry Pi:

Unfortunately, I’m not sure about the support on the Jetson Nano for the Raspberry Pi Camera Module. If it supports it, excellent.
I vote to change the Grove - IMU 9DOF (ICM20600 + AK09918) for the Grove - IMU 9DOF v2.0 - The last is a more recent and updated version.
I vote to change the Grove - Temperature and Humidity Sensor (SHT31) for the Grove-Temperature-Humidity-Pressure-and-Gas-Sensor-BME68 - It adds more sensors like pressure and gas, which would feed/fit more AI and machine learning applications for weather, air quality, etc.
I vote to change the for the /I2C-LCD-With-universal-Grove-cable - It would be great to have a “bigger screen” as part of the kit. Also, it is a graphical display - More information to display 
And about the Grove - Mech Keycap - Do you have any option for some module with more buttons available? I was thinking in something like this guy here: http://wiki.seeedstudio.com/Grove-I2C_Touch_Sensor/
The ReSpeaker 2 is a good choice, >BUT< it will limit the usage of other IOs and more features of the Kit. I see that you tried to “compensate” that with a I2C Hub. (Also, I’d suggest for another version of the ReSpeaker 2 to continue to expose the GPIOs from the RPi).
See this guy over here to see what I’m talking: GrovePi-Zero-GrovePi0
For now, my opinion is to maintain the ReSpeaker 2-Mic Array, as it is our “source” for audio and speaker for the board.
One question:
The Raspberry Pi 40-Pin Female Header is to increase the size of the connectors, because of the Jetson Nano heatsink next to it?
