Well, for the same reason a diavel isn't a cruiser. Well, one of the reasons. Cruisers are not just considered such because they sit low and have forward pegs and all that. It's also the engine. Thy are usually twins, and they are tuned very differently than the triumph triple engines with a lover CR/shorter stroke and are designed to produce a ton of torque very low in the RPM range while sacrificing HP to get there. The feel is about as different as a tractor compared to a Porsche. Putting a triple in a america would be like putting a V12 jag engine in a work van. It;'s just something no one does because it's a odd combination that doesn't fit any category. A cruiser is also heavier than a typical sport bike for example and a high revving engine like that wouldn't pull a heavy bike well with the torque up high in the RPM range and lower torque to boot. For example, the diavel has lower torque that peaks at a much higher RPM than a Tbird even tho it's a much faster bike.
Speaking of which, i have no doubt the diavel is a blast and i know it's deadly quick, but if thats what i wanted i wouldn't have bought a Tbird and might have bought a Vmax, Vrod or speed triple or such. They're all much quicker and i could have had the ST for much less. But none of them including the diavel have any resemblance to a cruiser. And as far as looks.....a soft shell crab could tell you the diavel isn't a cruiser !
And sure the america can be made stronger. But so can the Tbird so it's all relative. After the minor changes i made which have mine surprisingly stronger than stock, you'd be hard pressed to bring an america to that point w/o serious modification and reliability issues. The point is get the one you want, but if you want the big power it's better to buy displacement because you can stay street legal and have as much or more as the smaller bike w/o mods, or you can mod and stay equally ahead of the smaller bike when both are modded.
