I don't think that's a valid generalization. It depends enormously on the funding agency and the place you're submitting the paper, respectively. You're not going to be able to do a good grant proposal unless you have a good track record of research, with multiple papers. So in that sense, a grant proposal supersedes a single paper. But, given that you've already done all those papers, a grant proposal is just writing, not new research, so it should actually be massively less work than doing all the original research that goes into a paper.
