Sorry, I didn't realize that implementation of other-project-prefix
can be changed to read the project before reading the command
with arguments:

  (defun other-project-prefix ()
    (letrec ((root (funcall project-prompter))
             (depth (minibuffer-depth))
             (echofun (lambda () "[switch-project]"))
             (around-fun
              ...
