2 hours for an international connection with baggage that requires going groundside is very risky at any airport in the world.

You can hop a ride on the back of Usain Bolt to get over to T2 fwiw, it will not matter if you get caught up in any delay at numerous possible points.

I would only do this is I considered the risk of the missed connection not much worse than sitting around for the extra 4.5 hours for the later flight.
