Not without breaking the (fixed) crossfire MultiGPU clocks again, no. The fixed and most recent (and working correctly as they should) kernal files that there are available (and working on legacy) don't have a *.cat for Win 8 unfortunately. So the driver is and always will be Vista/Win7 x64. Sorry, but I just don't want to put a driver out there with broken 2D/3D clocks on the second ASIC unlike AMD. It was one of the reasons why I solved this problem plaguing 12.6 at the start, having as I do a MultiGPU 4870x2. I don't want to break the clocks again just for the sake of putting out a Windows 8 driver. Sure I could add the Windows 8 .inf from 12.6, but then there is no .cat file for the working kernal files. So the driver install will then fail because they won't be signed. You could sign the driver files yourself using DSEO, but they wouldn't work on anyone elses system apart from the one you signed them on.
