Enemy Territory: Legacy

Besides Enemy Territory (see https://portableapps.com/node/960 ), I was wondering whether the Enemy Territory:Legacy game could also be made portable ? There's all ready a portable version of Enemy Territory : Legacy (see http://www.portablelinuxgames.org/?id=wolfenstein-enemy-territory ) but that version is for linux only (not windows). By making a portableapps version of ET:L, it could also work under Windows. ET:L is quite similar to ET, however the engine has been improved considerably, see http://www.etlegacy.com/
