I posted this on the DIY board, but I'm hoping some of you wonderful ladies can help as well

Our wedding theme is peacock (but I would like to throw in a vintage twist). Our colors are navy, avocado green, and purple (medium to dark purple...but I haven't decided which will look best). My original idea was to recreate something like these:

For the second one, which is my favorite of the two, my plan was to replace the pomanders with off-white mini lanterns (with LED tea lights inside). However, manzanita branches are super expensive, even wholesale from a site like bloomsandbranches.com. We also decided on a different venue, and this one has 8 person rectangular banquet tables as opposed to rounds, so I don't think a tall centerpiece like this will work.
I know ladies on this board have amazing imaginations and creativity, so my question is: what else can I do that will incorporate peacock feather and/or lanterns, and maybe have a slight vintage feel? I am open to any suggestions. I want to make them myself, and I'm opting for non-floral in the hopes that I will save some money.
TIA!
