What you are proposing only makes sense if Intel doesn't receive backlash from Microsoft.
Microsoft's primary leverage against Intel is its ability to instill fear in PC OEMs who are Intel's primary customers not to get on MS's bad side.
With MS starting to compete directly against PC OEMs that leverage diminishes to the extent that OEM fear of MS turns to anger and rebellion. I think OEMs are now a lot more open to possible Intel initiatives to enable a non-Windows based PC software environment. IMO a good first step would be for Intel to state a new company policy that optimization/power state/ driver etc support for its new processors/iGPUs will be provided at the same level and time scale for both Windows and Linux.
