Found this product on the Blick Arts site: Schmincke Ready-to-Use Acrylic Binder (http://www.dickblick.com/products/schmincke-ready-to-use-acrylic-binder/#description).
This ready-to-use acrylic binder is ideal for producing your own acrylic colors in small batches. Just add dry pigment to the binder and mix with a palette knife, using a simple mixing ratio of 1:2.
No longer will you need to produce large quantities of colors. Now it's simple to make new and fresh colors as you need them!
The acrylic binder is lightfast, non-yellowing, and can be thinned using water. Blend pigments with retarder prior to adding the binder in order to slow down the drying process. This binder contains pure acrylic dispersion and a wetting agent.

Intrigued about the possibility of creating my own figurine paints using a variety of powders...
Would this work with ground dry acrylics, such as those GW paints in the horrible bottles? Instead of drops of distilled water and/or isopropyl alcohol or acrylic extender, could the binder be used to revive congealed acrylics?

These are the only Schmenges that I know of.

Sounds like any other normal acrylic medium with added flow-aid, which should be miscable with pigment. A quick google shows that people do this, with the problems of water-repelling pigments, and the acrylic medium drying out too much while mixing. Both seem addressed by the Schminke blurb, though.
I'm not entirely sure it'd be suitable for reconstituting dried or congealing paints. I think the former would have to be ground very fine (if I read you right) to avoid obvious grittiness, and good luck doing that with rubbery acrylic. If it's possible, I think the effort needed would just make me suck it up and buy a new pot from GW, even if the tragic loss of that whole £2.50 or whatever means my family will go cold and hungry this winter. Not to mention you'd effectively be diluting the pigment in the dried paint all over again. I'm not sure what effect that would have on opacity.
I'm no expert on the acrylic drying process, but water might be more effective with drying paints: you're replacing water that's evaporated, nothing else. Adding fresh medium will replace some water, but you're also adding a lot of acrylic and no extra pigment, which will probably reduce the opacity once again.
