The most simple way to accomplish that with C-x r b is by specifying
in CONDITION of 'display-buffer-alist' a function which delegates the
buffer display to 'display-buffer-pop-up-frame' provided the major
mode of the buffer shown in 'minibuffer-selected-window' is a mail
mode and to 'display-buffer-pop-up-window' provided the major mode of
that buffer is a markdown mode.  No need for additional commands or
keybindings.
