Maybe a W9 would be okay
A W8 isn't possible though because each 4 cylinder engine is inline, not a 'V' engine.
VW does the W12 engine because its development is fairly cheap (it's Siamese V6's joined at the hip ) plus it may have some packaging advantages over a looooong V12.

Because "V" engine are already complicated and pain in the *** to work on, as compared to "Inline" and "Straight" engines. The only advantage of a "V" engine is that its more compact when compared to "Straight" and "Inline", so when it comes to 8-12 cylinders you're pretty much stuck with "V" configuration. And the only time when "W" configuration is necessary is if you have 16+ cylinders.

I don't think so. The cylinders are at the bottom 'valleys' of the W, not the tops. The connecting rods are the lines of the W and the cams at the top. An "M" configuration might have 3 banks of cylinders.

I don't think it works that way. The W engine is essentially two V engines side by side. On a V engine you have odd/even cylinders interleaved controlled by 1, 2, or 4 cams typically. I think in the W engine the 'peak in the middle' of the W is the common cam of both V's if that makes sense.

Yea there was a Passat W8 for about a year or two, but didnt sell to well. I believe the cylinders were built on top of one another. I remember them saying the W engines were actually more compact than their V engines.

Forgot about that, you're right! Good one.
And a few cars have had V4's so the W8 is made from two V4's sharing the middle crankshaft.
