rrdtool 1.3.x at least has a resize function

NAME
       rrdresize - alters the size of an RRA and creates a new .rrd file

SYNOPSIS
       rrdtool resize filename rra-num  GROW|SHRINK rows

DESCRIPTION
       The resize function is used to modify the number of rows in an RRA.

       filename
               the name of the RRD you want to alter.

       rra-num the RRA you want to alter. You can find the number using
rrdtool info.

Looks like it is available in rrdtool 1.2.x too
