You cannot change the i2c pins to any pins you want. An i2c device has to be on i2c pins.

I run into the same issue because PIN 5 on my nano are occupied by freqcount library and can be definetly not changed to another pin because of this "interrupt" thing ... so this pins is not available for me to use SCL.

In the meantime, this pull request has what you want (example for SDA/SCL on 5/4): ESP32/ESP8266 I2C Clock Speed 800kHz & user-definable I2C GPIO Pins
How to get it:
- git clone library into your arduino library folder
- check out above pull request locally (e.g. see Checking Out GitHub Pull Requests Locally)
- initialize display with something like this:
display.begin(SSD1306_SWITCHCAPVCC, 0x3C, 0, 5, 4, 800000 );

TwoWire pointers are now supported - if you make a Wire object that is compatible it will work!
