Yes. Is it not more straightforward and comprehensible to say:
(1) OA is preferable to TA for the author-institution because it
maximises the impact of the author-institution's own research output
(and the rewards of impact).
(2) OA is preferable to TA for the user-institution because it
maximises the user-institution's access to the research output of all
other institutions.
(3) OA is more cost-effective than TA to institutions because: (a)
it costs less money and (b) it provides far more impact and access for
that less money.
But calculating the cost-per-download (to the user-institution) in OA
(when the cost is nothing) and comparing it to the cost-per-download
(to the user-institution) in TA (when the cost is real and substantial)
is (I think) needlessly straining to compare apples with oranges.
The cost-effectiveness of OA is best reckoned, and understood, as the
increased (indeed maximised) impact and access it provides. The monetary
measure of this is not download dollars, but the research and other
revenue that is generated by an institution's research impact (and,
more indirectly, the revenue from the enhanced research productivity of
researchers better informed about relevant research because they have
open access to it).
Downloads per dollar spent on OA vs TA just seems like an awkward way
of saying impact per dollar spent, especially since it's not the same
spender in the two cases!

When corrected to author-institution and user-institution, this can be
seen as download impact per dollar spent by institutions as a whole, in an
OA system vs. a TA system. This seems right, but again just a rather awkward
way of saying the OA is cheaper *and* generates more impact.
(I think the actual estimates of *how much cheaper*, based on BMC download
statistics, are probably somewhat arbitrary, because there are no good
download statistics for the comparison group. Hence citations are a more
reliable measure of impact. But I don't think anyone would dispute that
toll-free access generates more access, hence impact, than toll-based
access! Nor that $500 per OA article [BMC] paid by one author-institution
is less than the average $1500-$2000 per TA article paid jointly by all
subscribing user-institutions.)

But is it really an additional measure? Or just the impact measure translated
into funny-money?

I think researchers might find it more compelling to think of how many
downloads and citations their work can *earn* them, rather than how many
their institutional dollars can *buy* them...
Besides, OA can already be provided by researchers and their institutions
immediately, without having to change cost-recovery models or to estimate
the cost-effectiveness of such a change: They need only self-archive
their own TA articles. The enhanced "cost-effectiveness" comes then
even without any change in the cost! This "green road" to OA leaves it to
publishers to calculate the cost-effectiveness of eventually changing
to the OA cost-recovery model, if and when the availability of the OA
versions cause cancellation pressure on TA; meanwhile researchers and their
institutions are already long-since providing for one another's OA needs.
