I don't think so. Speculations about "fourth spatial dimension" were quite common in the time of Wells (almost as now). The Idea to put time to the same coordinate system as spatial coordinates was obvious and trivial if not for Euclid then for Descartes for sure (remember those school graphs of distance vs time). What stated Wells is "look, they are similar: all are measurable. If we can change our coordinate in space maybe with some device we can arbitrarily change our time coordinate". What came from Einstein's mathematics is: "time and space positions are not independent values but mixed up in a special way". I don't see why it can be the same.
