Wait a second... check out Wudan's Dragon, it lets you create animations. Forget messing with JK2's GLA, it will just up your file size (there is no need to include such a big file for only a few of the animations!) www.mt-wudan.com
(look around the forums for download links.
I noticed that while some animations are listed in JKA, Raven didn't import all of them from JK2.
