Is there any overlap with Dewey Larson's concept of nothing but motion?

Possibly, but AFAIK Larson himself did not attempt to fit his conceptualizations along these lines. Instead, due to his understanding of the reciprocal nature of space and time, he focused on explaining physical phenomena beyond the Newtonian conceptualizations in the regions of the 'very small' and 'very fast' (which currently fit under the Standard Model and astrophysics). But as far as I know, there is nothing in his RS framework (the fundamental postulates) that would preclude Tesla's theories from being derived from the first principles of scalar motion, if someone was willing to undertake that effort.

BTW, one theoretical construct which has attempted to describe physical phenomena along the lines of Tesla's thought is 'Aether Wave Theory' (AWT).
