I would particularly highlight that the GPLv2 is incompatible with GPLv3, which
is the license of GNU Emacs (and most Emacs Lisp packages).
The main file of this project says:
;; This program is free software; you can redistribute it and/or modify
;; it under the terms of the GNU General Public License as published by
;; the Free Software Foundation; either version 2 of the License, or
;; (at your option) any later version.
So this upgrade is unproblematic, as the "either version 2 of the License, or
(at your option) any later version" part explicitly allows it. In particular,
you do not need to ask for permission from other copyright holders to do it, as
you already got their permission when they distributed their code under the
above conditions.

Please consider upgrading the license to GPLv3.
