Mecanum drive train idea.

[MCeGEAR]

While at school i came up with an idea for a mecanum drive train that uses 8 mecanum wheels, no omni wheels used.
/1 \5
\2 /6

/3 \7
\4 /8

wheels 1 is connected to wheel 3 and wheel 2 to 4. Wheel 5 to 7 and 6 to 8.
Now, do you think this would possible work? and would it be superior to a traditional 4 wheel or some how just not work at all? Thank you very much in advance.
