[Opinions] I agree here

I think the slight sound variations on the names makes it feasible. The BETH of Bethany is much more pronounced, for me, than the -beth of Elizabeth (which is more like "Elizibith"). So it could work... as long as they both don't end up as Beth, as itsnotmykitchen says! Elly and Beth would be darling, or Liza and Beth. Beautiful combos!
