I think "competition" is being used to accept lessor standards Perhaps we should take "competition" out of the discussion. Instead lets "go" with what we have.

Our options are original Howdahs. They are PRICEY and have limited availability
The Pedersoli Cap Lock a bit less pricey and LARGE caliber; but available
The Pedersoli 45/410 runs from $1500 to $2000+. The cartridge options are small by Original standards; but is a HOT 45Colt really anemic?

Can two shots with a HOT 45 Colt stop a Tiger at bad breath range? I suspect we'll never know; but I wouldnt hesitate to use it on a charging pissed of Wild Boar at close range, (ask me how I know) OR for that matter a Black Bear climbing up to my tree stand. Im not into ballistics like some of you guys; but Im guessing a 3" Brass case 410 can be loaded pretty HOT.

So it seems the Pedesolis are the only real options. IF thats the case, then how can we make the best of what we have....modify the stock? rebore to 480 Ruger, possibly a 500 Special. (On that note a hot loaded 500S&W is a 10" Encore is quite a "handful". Adding the weight of second barrel might help IDK, using a lighter load would certaonly help and be more inkeeping with period loads.)
