Animation swapper/renamer for 3.X ?

[Knuckles_]

I know the old Glitchy's MES had an animation swapper, but since in LK it doesn't work anymore..

Is there any application currently available working with LK M2 Files (if animations are still stocked in those) in order to either swap them around or just rename them?

I'm working on a bunch of druid form model changes.. but some creatures have the good animations but they're not named correctly so they're not doing it (just using the default stand animation) and it doesn't really look nice.

I'd rather have some way to edit the M2 directly over converting and opening in 3DS for example, do the changes then converting and importing back.

Thank!
