Kaveri APU Crossfire on an ITX board?

I'm looking to build a new computer based around the new A10-7850k. I'm either going to go with the Gigabyte G1 Sniper ATX board or try to build a smaller machine using an ASRock Mini-ITX board. The deciding factor is if the ITX board can support crossfiring the APU with a dGPU. It seems not to be a common practice, probably because hybrid crossfire wasn't great before but it seems more promising with the GCN capable Kaveri APUs. I just want to know is it possible?

I think the economic argument isn't great right now. The A10-7850K is supposed to be around $175 and the R7 240 starts at around $70. You'd probably want a decent motherboard, the G1 Sniper you mention is $110.
Total - $355

By comparison-
FX6300- $110, 970 Motherboard - $75-100, GTX660/R9 270 - $160-180.
The second build is going to blow the first one away in pretty much any task.

Now, if you drop to ITX, AMD loses all of their AM3+ offerings, and things get a little more interesting, but I'd still be more inclined towards a basic i5 build.

I'm not sure that a GDRR5 Dual graphics solution makes a lot of sense.

There shouldn't be any reason you can't do this on ITX, I think the question is why you would want to, at the moment.
The results from the limited Kaveri reviews seem pretty promising with regards to Hybrid crossfire, but for me the cons still outweigh the pros.

Because I can do so cheaply, don't have a big budget at the moment and the results seem promising. I just hope better drivers are pushed so crossfiring is supported with more than just the R7 240 and 250. Would like to use an HD 7750 or R7 260x

I would expect the best performance you could get out of this build (with newer drivers) would be OC the CPU to 4.5 maybe and pairing it with (surely) the R7 260X or (maybe) the 270X.

If you don't plan to OC, just get the A8 7600. The A10 7850k has that premium I think mostly because it is more overclockable. Also the more capable GPU should show its wits in time with better drivers.

I was planning to overclock the CPU to 4.5 that was my other concern with an ITX build would be cooling.
