It's a fantastic tree! Good luck with your new planting. Sunburst Pine at the home of Allan Taylor, who discovered and introduced the tree. Picture taken June 12, 2011.

If you are willing to think beyond the starburst shape.... Lowes and HD each have several different styles and sizes of ceiling medalions. You could buy 1 of each style and add your own mirrors to the empty center area. Paint them w/ gold craft paint and/or do a dry-brush finish w/ black in order to antique faux finishes them. There are seveal shades of gold paints out there, so they could all be the same or have a few that are different. The round shapes could act as a nice continuation of the mirror at the base of the stairs.

I read the article, and perhaps I missed something, but it didn't allude to anything that I noticed. It clearly stated that the sunbursts were halos that had decorated the statuary. But perhaps monstrances/reliquaries also suffered the same fate. I am not Catholic, but I am thinking that the objects (like a monstrance) are not sacred, they are merely containers - only what they hold is sacred. And since according to what I read about the Roman Catholic stand on consecrated objects, once they are destroyed or removed to secular use they are no longer considered consecrated, those items have no sacred meaning once they become converted. Like a church that is sold and becomes a restaurant is no longer considered a consecrated place. However, the lack of respect for the faith of others by those acts of destruction is to be abhorred. I think the sunburst mirrors are nice, and can add a fun or dramatic touch, but clearly they are overused, and sometimes stuck up on a wall in places to which they are not well-suited.

Yes, you can do that. The bath bar style is fine but if you choose a vanity light, a two-light fixture is better with a 60" vanity. A four-light fixture is enough light if you want to use just one light above the mirror.
