45 Colt / 410 Shot / 454 Casull - Why not interchangeable 3 ways?

BFR and the Thunder 5 are chambered in 45 Colt/410 shotshell. As far as I know, all 454 Casull guns can fire 45 Colt as well.

So why is it that we don't see guns chambered for 410, 45 Colt, and 454 Casull all at once?

A cylinder long enough to handle .410 shotshells but with thick enough chamber walls to handle .454's would be excessively heavy.

That thing about the pressure spike is just retarded. If that were a reason to not make a .454, we wouldn't have .454's.
0.454 has intense pressure requiring a tough chamber. .410 requires a long chamber. So far no one has put the two together.
