Would a dual wb be of use?

[RUMbleBUGgy]

I recently had an innovate mtx-l fail on me. I've been considering a megaspartan dual wb module. The CAN connectivity is drawing me to that but I'm curious if i really could take advantage of multiple wb's seeing as my engine is a straight six with a log type manifold and semi sequential injection.

I suppose the second wb could be to check against values of the first, but would there be any other advantage to having two in series say a foot or two away from the downpipe downstream from the first wb? Would the ego be able to blend between the two sensors?
