And? Neither sounds "cheap" as you said in your first post. This won't be a cheap transformation by any means, unless you consider an S63 a cheap upgrade of an N63.

This very innovative charged-pulse system of the S63Tü only works on V engines, because it needs the cylinder outlets to be close together, so that the way for the energetic exhaust gases are relativ short before the reached the turbo scroll ... totaly impossible in any way to be adopted to an I6, where the distance between the first and the last cylinder is very long !!!
They aren't really that close:



The red and green paths in particular have long runners.

I don't believe for one second that it would be "totally impossible" to do something like this with an I6.
