Perhaps NH should consider making a 6cyl version of the t5070, the cab would be a far nicer place to spend a day than the old super comfort, and the back end wouln't be too dissimilar, although the 6cyl engine may place too much strain on the drivetrain etc. NH would prob argue that they've already got this end of the market covered with the t6030 delta with mechanical linkage controls, not sure if there's a 12speed gearbox available without dual power, but this could be specified on the TS115A and I even saw a12speed TS100A without the powershuttle for sale in J Brock's yard, it had what appeared to be a synchro shuttle gear stick on the LH dash. I don't think the market for a basic tractor would be enough to justify any more R&D than a 6cyl T5000.
