That's roughly what you're already doing.
Try enabling the extendedtime=yes option in the routers2.conf, which will allow you double-data-width graphs (IE, 2 years to view) which represents the entire length of the RRA data available in RRD files generated by MRTG in later versions (earlier versions only had RRAs just over a year long).
The default MRTG-generated RRD file format maintains RRAs (rolled up data archives) corresponding to Daily, Weekly, Monthly and Yearly with 800 data points (400 are on a normal graph) and so it is not actually possible to have graphs going back further as the data are expired as they drop off the end of the fixed-length RRA.
Another problem with doing this would be that a lot of sanity-checking would be needed on data windows, plus the axis labelling would be awkward to be sure of (do we label in hours? days? etc...)
