Sure it could, It would be hard to get it to shoot better but do able but they could start by making it available in good quality stainless and with an adjustable trigger a bit better design on the stock with different thickness but plate to change the length of pull. A spring backed pivot point so that wear or tolerance did not affect the group shooting capability and a 45 degree lock up with a lever and spring system that was strong enough to really lock it in place [ Triumph's is good but easily improved on] any good gunsmith could show you many ways to improve on the Triumph.
I believe that the biggest problem with modern design is that engineers are doing it they understand many things but the intricacies of barrel whip and accuracy are not taught in school if they severed a 7 year apprenticeship working on guns under an old Master they could learn things they have yet to even hear of.
