More tinkering with autoit, tes3cmd and perl...
aceg
Animated Containers Expansion Generator
by abot
Uses tes3cmd.exe to generate "MW Containers Animated exp.esp" to
add animations by Arcimaestro Antares/scripts by qqqbbb to related
containers having no script in your modlist.
Prerequisites:
tes3cmd.exe, aceg.exe, aceg.pl must be inside Data Files folder
Required mods:

Load generated "MW Containers Animated exp.esp" as last as possible,
right before merged objects and leveled lists
E.g. suggested procedure:
1. run aceg to generate "MW Containers Animated exp.esp"
2. generate your Merged_Objects.esp and load it after "MW Containers Animated exp.esp"
(I think also NOM should be loaded after Merged_Objects.esp)
3. generate your multipatch.esp and load it after "MW Containers Animated exp.esp"
e.g. suggested MLOX loading order:
MW Containers Animated.esp
MW Containers Animated exp.esp
Merged_Objects.esp
NOM3.03.esp
NoM_CoM Compatibility Patch.esp
NoM_Creatures Loot Standard.esp
NoM_BF Compatibility Patch.esp
NoM_MC Compatibility Patch.esp
RoHT NoM Addon.esp
Owned Beds NOM.esp
Merged_Leveled_Lists.esp
Mashed Lists.esp
multipatch.esp
