Could I setup a non-profit org. with only the purpose of collecting donations then transferring those funds to another non-profit to put to use?

Could I setup a non-profit organization that conducted mailing campaigns to collect donations for a worthwhile cause, then simply hand over/transfer all those donations to a larger organization to put those funds to work? For example, a mailer campaign for breast cancer then donate the funds collected to http://www.nationalbreastcancer.org/ (after covering the mailer costs)? I''d like to make the effort into the collections aspect of a cause, but not the nitty gritty of deploying them.
