Seems to me there's a nice option with Allison-biased Mosfets.
If you you drive the Allison at the emitters and use bootstrapped current sources, then you can get close to rail-to-rail output voltage swing because the gates can be driven beyond the supply rail voltages.

All this depends of what Sig wants.
I attached a zip file holding the schematic and files for that experiment at the bottom, if you can use LTSpice. I'll look for the image.

In your Allison thread, the image in the first post won't expand , so it's hard to see what's going on.
