If the sabot won't perform with smokeless then I really don't see any benefit in making it from a financial view for them. The barnes and 200 grain sst are not in any need of a sabot and I suspect that the bloodline bullets are not either. So really it would only be providing just another option in the rare case you can't get the Harvester blues or MMP tans to shoot well. So then you have the PR bullets that it "may" benefit?
As far as a 230 grain Bloodline goes, the only people that have them are the couple people on these forums that are "testing" them. I don't expect it to come out anytime soon if ever because from a financial standpoint for Knight they have to make an actual gun that will shoot them before they can produce the bullets to sell to the public. I suspect they struggle with that thought because do they want another .52 type gun that the majority of muzzleloader shooters will never get on board with? The general public of shooters knows .50 caliber 1:28" twist. Period.
So if this "super" sabot will hold up in a smokeless gun along with a couple .40 cal bullets that are made in the 220-240 grain range it might have a chance. Anything else is just dreaming really. I hope I am proved wrong on all counts (really I do) because I personally want to see heavier, longer, premium .40 cal bullets compared to what is available today along with sabots that will hold up in smokeless guns.
