It got me wondering if running a stiff outer spring would allow for keeping the "shock absorption" feature when applying the rear clutch, while also providing some mechanical assistance with the line pressure to reduce the time for the piston to top out into the case when the front servo is applied...
You're thinking correctly...
Source(s) for springs from which to select? I don't have anything in my trans parts boxes that appears to be an accumulator spring, and suspect there won't be one hiding under the valve body when I pull it, either.
