[Please Help] Is there any way to downgrade 'preview'?

[vmflapem]

I like the Mavericks version of the Preview MUCH better.
Is there any way of downgrading so that only the preview is downgraded?

I do not have any backups from Mavericks...

Please downgrade to Mavericks - clean install... Forget about porting Preview from Mavericks to Yosemite...

And welcome to your worst nightmare...!
