Sounds like a good idea, I don't know that a MP game without the 3d views will work very well, sticking with the 2d view will not get all that much interest from a lot of MP vets from other games.
People might prefer to play with the 3D viewpoint locked on the commander.
They might do, but they might not.....why play a huge scale, massive game, if all you can see is what's happening within a few hundreds yards.....each to his own preference of course, but I thought the whole idea of LG was the large scale of the game - which will be lost if you can only see a few hundred yards. From a big hill he might be able to see a mile or so, so it's not as bad as I say above, but you get the idea....I'm sure most people will want to be able to view any part of the battlefield, from their own troop positions of course.
A game is after all, a game, that people want to enjoy, MP is not going to be easy to arrange and those that take the time and trouble to play it will want to enjoy it.
I have not seen much evidence yet on any of the many forums I use that MP is going to be popular, SP sure will be, no doubt about that, but interest in MP games appears to be very slow, even after we have seen a demo.
Maybe everyone is waiting for the real game to get interested in MP.
