The only thing that is useful from those assemblies is the reverse spiral center section, that's where all the strength is. Otherwise, it's just a heavier (weight-wise) D44.
A kingpin axle would be better for overall strength, though a Tacoma isn't exactly a fullsize, big-blocked beast. As Zac said, the kingpin knuckles are far simpler to set up for high-steer, because the top of the knuckle is above the inner knuckle.
Crane High Clearance offers ready-to-rock kingpin high-steer knuckles that are super beefy. Of course you would also need the inner knuckles to make it all work, but you would have a very nice setup.
Crane even offers reverse spiral center sections so you could basically build a complete axle.
