Not Exactly how you want it...
I used just the core rules method (IE, no task rolls needed), and it worked just fine.
See, let's take Zh TP marines.
Under CT, they could get over, maybe bypass a door or two OR go back.
Under MT, they could do the same, but it might take them a few tries.
Under TNE, they might not all make it in one jump, but away they'd go, get there in small groups, and then be able to bypass any door if the Clairavoyant and the telepath are still functioning.
T4 core is more like CT: you pays your points, and it works.
T4 PsiHB makes it more like the MT model.
On task consolidation: I just collapsed Tasking and Impossible to the MT impossible.
