PCA9306: Swapping SCL & SDA

Part Number: PCA9306

Hello,

As far as I can tell, the circuits for SCL and SDA channels appear to be identical.  I want to swap the lines for layout reasons, but I'm worried I will encounter some problem.

So, for example, current layout is:

MASTER_SDA <=> SDA1 - SDA2 <=> SLAVE_SDA

MASTER_SCL => SCL1  - SCL2 => SLAVE_SCL

I want to change to:

MASTER_SDA <=> SCL1 - SCL2 <=> SLAVE_SDA

MASTER_SCL => SDA1 - SDA2 => SLAVE_SCL

This shouldn't cause any problems for I2C @ 400kHz translating from 1.8V to 3.3V, correct?
