That approach might be more palatable to some creationists, but, I think, only with one important feature: man would need to be at the very tip-top and center of the tree. If some cyanobacterium was in that spot, in keeping with their relative influence on the history of the planet, and we were over on some little side branch of the big bush of life, I don't think creationists I know would be very impressed. And either way of presenting the data should be perfectly valid - we just like to think we are the important ones.
"The wretched world lies now under the tyranny of foolishness; things are believed by Christians of such absurdity as no one ever could aforetime induce the heathen to believe." - Agobard of Lyons,
