NOT TRUE!
I've made double sided toner transfer boards with SMD parts having 0.5mm pin spacing, which is more compact than what you did. The trick is to use a good toner transfer system such as the press-n-peel blue available from allelectronics.com I etched each side of the board separately protecting the reverse side with a layer of spray paint (removed later with mineral spirits). I drilled a few holes after etching the first side and used pins to align the second side transfer sheet while ironing it on. I got very good alignment between sides. I did have to use wires between sides as you can't home brew vias!
