By the way, thanx for your interest for the idea  |
The thing you have to consider is the response times of the two screens.
The LCD has a many times faster response than the e-ink, therefore if you were typing on it you would be typing blind or have to adjust your typing speed to the response of the e-ink - I also think the e-ink would have to refresh for each character.
By typing on the e-ink you would be using the wacom tablet as the input device - the e-ink display would have a static keyboard image. In fact once you had a key template and position mappings you could use whatever keyboard you liked - even make special keyboards if necessary.
In fact I have several templates for inputting mathematics and chemical formula that I use on my Acecad digitiser.
