Not much, but a little. In a state with mountains running its entire length, your source specifies that economics aren't favorable for the development of pumped hydro as of 1979, why would you think it is more favorable now when a much less expensive alternative has been developed? So to answer your question, I can sell them v2g because even with all that pumped hydro potential, the v2g is going to provide a better cost/benefit ratio.
The problem you're facing is that you still haven't dredged up either a comparative analysis across storage mediums nor a national/global analysis of the distribution of easily developed pumped hydro sites. Remember, we can build the infrastructure for pumped hydro nearly anywhere if we have unlimited funds - which is the concept you seem to be arguing from.
Here are couple of hits from the google scholar search /v2g pumped hydro wind/

Abstract
One of the unique advantages of plug-in hybrid vehicles is their capability to integrate the transportation and electric power generation sectors in order to improve the efficiency, fuel economy, and reliability of both systems. This goal is performed via integration of the onboard energy storage units of plug-in vehicles with the power grid by power electronic converters and communication systems. Employing energy storage systems improves the efficiency and reliability of the electric power generation, transmission, and distribution. Similarly, combining an energy storage system with the power train of a conventional vehicle results in a hybrid vehicle with higher fuel efficiency. In both cases, the energy storage system is used to provide load leveling. In this paper, viability of utilizing the same energy storage unit for both transportation and power system applications is discussed. Furthermore, future trends in analysis, design, and evaluation of distributed energy storage system for the power grid using power-electronic-intensive interface are identified.

Wind
The use of wind energy for electricity generation has grown dramatically with decreasing
costs and improved performance of wind turbines, increasing fossil fuel costs, and
growing environmental concerns. The United States has a large wind power resource
base, exceeding the current installed electricity generation capacity from all sources. The
development and use of this power resource is limited by a number of factors, including
the location of high-value wind resources, the resource variability of wind energy, and
the relatively low availability (measured as amount of electricity actually
generated/maximum electricity available, if operated continuously at full-rated power) of
this generation source, compared to conventional alternatives.
Variability in wind output implies limited predictability; high natural ramp rates; and,
often, limited coincidence with peak demand. These factors can restrict the ultimate
penetration of wind power into traditional electric power systems. The high reliability
required by such systems dictates that ample capacity is always available and that
conventional generators are able to follow the variations in loads, forced outages, and
variable supplies like wind. Where wind power adds to these capacity requirements, it
usually incurs additional costs.
One possible solution to the problem of variable wind output is energy storage—the
application of any of several technologies that can store electricity when it is not needed
—and that can deliver stored electricity when demand is high, or renewable output is low.
The United States currently has about 20 GW of pumped hydroelectric storage in place,
with further expansion restricted by lack of available sites, environmental issues and high
cost. While there are a few other options, such as compressed air energy storage, 1
these technologies all add significantly to the cost of electricity to be stored.The optimal solution for wind would be coupling it with a low-cost source of energy
storage (or dispatchable load) that is perhaps already in existence for some other purpose.
The emergence of “plug-in” hybrid electric vehicles may provide this significant
opportunity....
