That's waaay too much cake for 150-175. What about this cake by Boween http://www.cakecentral.com/modules.php?name=gallery&file=displayimage&pid=636183

You could show it to your bride and see what she thinks.

If your 12" cake is on a 12" plate, I don't think your fountain will fit between the pillars. You'd have to use a 14" plate under the 12" cake (and under the fountain) for the fountain to fit.

I've done fountains that sit on top of cakes..... you do them no different than you do for cakes ... good dowel support under the plates and you're fine.

Here's some cakes I did with the fountain between the tiers:
