@Swimpy,
Love what you've done, Swimpy.
We don’t have standard night tables at home either. The bed is 26” with an antique washstand (maybe washstand isn’t the right name) on one side (28”), and a small chest of drawers on the other (29”).
We do have matching night tables in the master at the cottage, but I can’t give you measurements from here. I’m guessing they’re perhaps slightly higher than the bed, but we opted for a low box spring there. In another bedroom there, we have a nightstand that I think is a little lower on one side, and a small chest of drwers that is a little higher on the other. Ha.
I think you're right, anything goes!
