3/60 & 3/80 hardware speedup query

When Sun shipped 3/80 workstations, it was with 100nS SIMMs. I don't
remember for certain, but 3/60 workstations may have even had 120nS SIMMs.
To make everything work reliably this would have necessitated quite a few
wait states on any memory access. Especially so with the 3/80, which
doesn't have the external cache of the 3/60.
So ... it seems that with the cheap 70ns and 80ns SIMMs that are now
available a workstation could run somewhat faster if the number of waits
were reduced to reflect the higher performance RAM.
Does anybody know if it is possible to make a simple hardware change that
will reduce the number of wait states ?
