May be the above discuss can be indicated as: external I2C master<--->FPGA I2C slave-----FPGA I2C master<---> external I2C slave. Like a protocol converter.

The description fits in terms of involved effort, but not for the exact functionality.

The converter needs to pass the response of addressed peripherals from second bus immediately bit by bit, clock cycle accurate.
