NO.

I wondered about this possibility before when first reading about your conversion, let me explain my thoughts:

The caliper bracket has a certain amount of surface area where it is clamped to the steering knuckle. The bolt provides the torque, but it is the friction of the two surfaces that keeps the caliper bracket from sliding. The bolt by itself is not strong enough.
When you put a washer in as as spacer, it would have seriously reduced the amount of contact surface area between the bracket and the knuckle. The new surface area is the size of the washer and this may not be enough to hold the caliper bracket from sliding. Then its just pressure on the bolt that holds it.

The best fix would be to have a spacer made that uses all the surface area on the mounting point. I would even recommend welding the new spacer onto the caliper bracket so you only have one frictional surface to deal with.
You already know the thickness you need, you should take the brackets to a metalworking or machine shop and tell them what you need. Maybe $30-50 later you could have a one piece bracket for you conversion.
