Suspension Geeks: Strut mount question

[ggehrke at gmail.com (GGehrke)]

As I mentioned a second ago in my other mail, I'm thinking of
modifying my suspension to get a little more drop without reduction in
travel.  I was looking at camber plates with spacers, but decided "not
yet" so here's what I came up with instead:

Would it be possible to cut off the studs on a stock upper strut
mount, drill out the holes where they used to be, and use bolts
instead?
And then, instead of mounting them on the underside of the strut
tower, mount them on top.
And for an added bonus, put a 1/2" or so plate between the strut tower
sheet metal and the strut mount.  I'm thinking you'd probably want a
reinforcement plate on the underside of the strut tower as well to
distribute the force of the bolts (this could potentially be made from
an old strut mount).

Here's a picture of what I'm thinking:

My questions are, though:
1. First off, is this an accurate portrayal of how the strut mount
fits together?  I haven't taken my scirocco suspension apart yet, so I
could be completely off base.  Keep in mind, too, I'm talking about
all this in context of aftermarket coilovers.

2. In the process of drawing it out, I think I debunked my own idea -
The spring would still have to seat on the underside of the strut
tower, so even if the shock were more extended, the spring would not
be.  Correct?

3. If #2 is the case, then how do camber plates with spacers work? 
Where does the spring seat?  Is it a problem?

Opinions?

I'm probably just going to install my new coilovers and new strut
mounts and call it a day, but I'm a huge geek with this stuff and
would love to tweak it to perfection...
