I'm trying to think if you could add metal to your nails and not look like a serial killer. You've got lots of lightweight aluminum and the tools to sculpt it. Then you could have a permanent set that you'd simply need to reapply every once in a while.

The last photo made me think of it. You could have a base of aluminum, then add the pink or red to make it seem a little less metallic.

Your nails always look amazing.
