I am starting to look at other options for LCDs too. Lenovo screens are good candidates, since they have pen support.
The MIIX replacement LCDs are really nice, although they run about $150. There is also the ElitePad 1000 G2 which is 10 inch but has 30 pin edp + i2c for touch and pen.
One more thing: video about hacking the wacom digitizer https://youtu.be/Zsaeg7UrHr4?si=KFLD7hjgeFHo99rB
It would be lovely if there was touch lcd compatible with the digitizers, since the protocols seem relatively documented and are available cheaply on ebay.
Finally schematic dump on the ElitePad LCD since there are schematics on iFixit website
