I wonder if electrostatic motors would have been as practical
as electromagnetic motors if the history of motor design had
taken a different turn a century or two ago.

 I think Philips dabbled with them many decades ago.  A report will be
somewhere in the Philips Technical Review.
 

Thanks for that hint. The Philips Technical Review is a treasure
trove of interesting stuff.
I found a paper by B. Bollée on electrostatic motors:
