Other alternative would be to go for the Chuwi like devices from China.
You mean Huawei MateBook? an early review said it missed the mark, it's beautiful like an iPad but fails the basics.
Huawei MateBook review: this tablet wants to be a PC, but misses the basics
Hopefully there will be a MateBook 2 and it will be better, competition is good.
Interestingly there are very few entrants in the space between 10.2 and 11.5 size. There are a raft of 10.1 devices and a sudden surge of 12+ devices but the Surface 3 has staked out a perfect size IMO that nobody is making.

Above 10.1 and below 12 there is:
Google Pixel C at 10.2
Samsung Galaxy Tab S 10.5 - although the newer S2 went to 9.7
Dell latitude 11 at 10.8 - but it's thick and ugly
And a smattering of eight 11.6" devices that go back a couple years or more, nothing relevant.
To me 10.8 is a ideal size and they could bump it to 11.0 in the same physical size similar to the change from SP3 to SP4. Given what Samsung, Huawei, and Toshiba have done with weight on a 12" size 693g, 640g, 579g an 11" device should come in at 580g and under 7mm thick. S3 is 622g and 8.6mm.
They could present a strong challenge to the 9.7 iPad with this in the enterprise, not too small like all 10.1 and under devices with the requisite cramped keyboards and screens, all while being fully capable. I would not be too hasty to abandon this size or worry in the least about using a core-m just because the low end bigger, heavier, higher resolution, SP4 has one. After all 9.7 & 12.9 iPads have the same A9X SoC. It's a win both Intel and Microsoft need so "Pricewise" I think they could find a way to get it done somewhere within their vast pool of resources.
