If that's really what you want, there is an easy solution.
Provide two packages with identical (or compatible enough for your
purpose) specifications:

package Binary_Tree is....
package Linked_List is....

Then declare at library level:
with Binary_Tree;
package My_Structure renames Binary_Tree;

And then, use My_Structure all over the place. By changing two words in
one two-line file, you can switch your entire project to the other
implementation.
