It might be possible if you're willing to make a couple of compromises: try
using 10-minute intervals instead of the default of five minutes, and also
break the collection process up into, maybe, 10 groups, launching one off
per minute.

Your crontab will be a little bigger, but you'll get less of a "death by
management" probability. :-)

FWIW, I think polling a 2900 for MRTG generates about 20k bytes of network
traffic per interval (very rough estimate from similar boxes I've done) so
you might use that figure to work on the impact to the network itself.....
