Surely. But this will turn out to be complicated. And personally, I'm afraid, that a documentation would turn less experienced users into using stuff they don't understand. And there are some drawbacks, especially when it comes to using 1 min polling with already existing rrd files. It will require a lot of tweaking around and fiddling with rrdtool command line tools.
Only for new setups, a quite straightforward walkthrough is possible.
Considering that we are trying to "fix" multiple polling intervals in 0.8.8. We have hesitated to officially publish documentation for something that might change in the future.
