Yeah, that makes perfect sense to me.
But unless I'm badly mistaken, neither the 2v or 3V engines have this aggressive cam you refer to. Isn't an "aggressive" cam one which provides more power in the upper RPM ranges which causes low RPM performance to be abysmal?
I always figured one benefit of having more cylinders per unit of displacement would allow the engine to rev higher due to the lighter mass of the individual rotating components. Again, not directly applicable to the V10s, as they aren't high-revving motors.

However, as I mentioned, the smaller cylinder helps with complete combustion. This helps with emissions on gas engines; again, I'm not sure if that was a factor when Ford built the V10 or not, I know it was when Dodge decided to go with their V10 8.0L in the Ram though.

well a v8 is the least efficiant engine built. its fights gravity. now a inline 6 is a more econimical engine. to bad they dont make them anymore in light cars and trucks. so i wouldnt imagine a v10 is better. it would be worse. you may make more power because you have two extra cylinders but that doesnt make it better.

the front and rear trio of cylinders are mirror images. creates a perfect balance.
a inline creates less torsion stress than a v8. thats why there perfered in large trucks. cant fight you on the room issue though
in the words of wiki "Because it is a fully balanced configuration, the straight-six can be scaled up to very large sizes for heavy truck, industrial and marine use, such as the 16 L (980 cu in) Volvo diesel engine and the 15 L Cummins ISX used in heavy vehicles.[4] The largest are used to power ships, and use fuel oil."

Interesting. I always assumed they built I6 because it was economical to build, but I guess there is that aspect too.

As far as balance, so? V12s and V16s have perfect primary and secondary balance at any v-angle, as does an Inline 8 and V24. Detroit Diesel has a 20L V8, Cummins has a 78L V18. EMD made a 211L V20. Balance issues have not stopped anybody from making huge versions of V8s and other weird number cylinder configurations.
You also still haven't told me why a V8 has to fight gravity...
No....Torsion is twisting. Inline 6s and 8s have much longer crankshafts then an equivalent V8. This means that the crankshaft is going to want to twist a lot more. The reason why they are preferred in large trucks is because of ease of maintenance and the ability to fit between the narrow frame rails of a semi.

Yes, they are very well balanced, or can be. That is why they are used in luxury cars as I mentioned above.

Like this kind of awesome?

To top that off it pulled the Boeing 747 in second gear. That's 150 tons for those that don't want to click.

im not try to say the v10 is a worse engine. im just saying that by calling it better beacuse of two extra cyliders is all in the way that you look at it. one way yes it is in the power aspect but yet in other aspects it may not be as good. fuel economy for one.
