Layering table drapes and runners?

Hello all-

I'm trying to figure something out - and I need to bounce some ideas around here. Our venue has 6' rectangular tables, with white tablecloths, and we wanted to put a square overlay on them turned on point, so triangles hang on either side. My question is - would it be too over the top to add a runner on top of that with our long-ish floral centerpieces/candles/displays on top, for a small-ish (60-75 guests) wedding? Or just overdone in general? I was thinking the runner & overlays would be various combinations of my colors (burgundy, chocolate brown & beige) to keep it kind of varied as well.

Any thoughts?

Thanks!!!
