If you're riding flats maybe hiking boots / shoes would do the trick?
FWIW staying warm rather than dry is more imporant.
I'd be inclined to go for windstopper style stuff rather than fully waterproof – you may get wet, but you'll get wet through condensation from fully waterproof stuff, brethable or not.
I think that with cycling you generate so much heat that staying dry is not possible – you'll get wet through sweat or rain whichever layering you go for. In the depths of winter I take a spare base layer and change when I'm wet.
I strugglell with gloves – they get wet or sweat gets them wet. I'll try windstopper ratehr than wterproof.
FWIW, IMHO, windstopper is better than waterproof – more breathable so less likely to get soaked through sweat, but will keep you warm once wet. Base layers with a shell style outer (of windstopper) and then either a mid layer as well under the shell, or a softshell when its cold.
