I have had some nice warm results using just a developer using Ansco 130 or the catechol print developer recipe from the Darkroom Cookbook. Of course all of those have stuff in them too, either glycin or catechol, that is not exactly good for you either. Seems you just can't escape from the chemistry in this hobby! But good luck to you whatever you decide to use.
Also, FWIW, the bleach that you mix up with the ferricyanide is a pretty weak solution. It is hard to imagine it eating up your sink or anything, unless you just left it there for a very long time.
