It's a reasonable idea. I have an ADS1115 at home, but I'm currently traveling. When I return I can do some tests. In the mean time, most I2C devices don't regulate their speed, so you can potentially run it at > 400Khz already without having to switch to high speed mode. The ESP32 lets you set hardware I2C speed up to 800Khz and my bit bang code can run at about 1Mhz, so give it a try.
I'm specifically looking for a way to improve data transfer rates with an ADS1115 which support high speed mode but only after
I've been stabbing in the dark but had no luck so far.

I'm running an ESP32 so believe the speed increase could be useful
