I didn't try this trick before but I think it may help,
You can select story elements and right click then Relink home story,
That will let you assign all elements to another story without changing element's height or elevation,
Then delete the original story,
Be aware : To be able to see these elements on floor plan you should change FPCP to exceed the story height in order to cutting those elements.
Edit: If the deleted story is the highest one be informed that all elements top linked to it will become not linked.
- If the story is in the middle sure it's deletion will affect the height of any element bridging that story, for example if a model has 3 stories (1,2&3) any element bottom linked to story #1 and top linked to story #3 - sure it's height will be shrinked if I delete story #2.
