Continuing with the discussion, I guess it won't be a bad option to have some sub-continent commentators on the board. I guess, they will be comparatively easier to get (and cost-effective too - no offence). But more importantly, it'll add another dimension to the game.
On the other hand, I think more than 'who are the commentators', it is of greater significance to add more permutations and combinations to have a dynamic commentary option. For example, if they have teamed up Ravi Shastri and Rameez Raja, and Jeff & Lawry, I guess it would be a good option to mix the teams a bit, e.g. Rameez Raja & Jeff. This will add another variety. In addition to that, changing commentators (and the combination of it) mid-games will also be important to keep the whole process fresh.
