Well, yes you could take Spontaneous Metafocus on a spell that you have Preferred Spell since that spell becomes spontanious for you. But you do realize that Preferred Spell already lets you cast at the normal casting speed, right? So if you metamagic your preferred spell and it normally casts as a standard action, it is still a standard action even with metamagic feats applied.
Anyway you slice that Sacred Geometry comes in behind it all and mucks things up. If you want the benefits from Sacred Geometry you have to apply the effects that it lists to the spell you are casting. If you don't apply the effects, you don't get the benefits. One of those effects is extending the casting time as if you were a bard or sorcerer adding a metamagic feat to the spell. If you don't do that, you do not get the benefit. That is literally what the second sentence in the feat description means.

Would Sacred Geometry not be a means to add metamagic feats and thus allow Spontaneous Metafocus to shorten the casting time?
Think I already explained this? Sacred Geometry is a process. If you lengthen the spell casting time and manage to manipulate your dice rolls into the correct sacred number, you get the benefit. If you skip either step, you get no benefit.
So you CAN cast the spell at the normal casting time, but that means you get no benefit.
Sacred Geometry is a ridiculously overpowered feat as written. And the few safeguards the author put into it force you to play by his rules or you get nothing. Stop trying to get more from it.
