Here you are. Couple easy text changes. Check it out in game, fully compartible with whatever saves/mods available
Initial idea by HellFell, some more animations by me.

For 95x and 960 versions of M&B with ragdolls Search for the following code in Modules\Native\actions.txt (or not native but module directory)
fall_head_front 1049602 1
1.20000 anim_human 40100 40138 17 0 0.00000 0.00000 0.00000 0000000

2.70000 ani_died 16 99 17 0 0.00000 0.00000 0.00000 1.8
and replace it with
fall_head_front 1049602 8
1.5 anim_human 40100 40138 18 0 0.0 0.0 0.0 1.0
1.9 anim_human 45453 45430 18 0 0.0 0.0 0.0 0.0

for 95x and 960 version with disabled ragdolls range of available animations is smaller, because only those ending with guy lying on the floor fit. Replacement code would be
fall_head_front 1049602 3
2.2 anim_human 40100 40138 17 0 0.0 0.0 0.0 1.0
2.2 ani_died 16 99 17 0 0.0 0.0 0.0 1.7
2.1 anim_human 45400 45423 3 0 0.0 0.0 0.0 0.5
fall_body_back 1026 3
2.7 ani_died 16 99 17 0 0.0 0.0 0.0 1.8
2.3 anim_human 45400 45423 3 0 0.0 0.0 0.0 0.7
2.2 anim_human 40100 40138 17 0 0.0 0.0 0.0 1.0
For 90x versions of M&B:Search for the following code in Modules\Native\human_actions1.txt (or not native but module directory)
fall_head_front 1049602 1
1.200000 anim_human 40100 40138 17 0 0.0 0.0 0.0
If ragdolls are enabled, replace it with
fall_head_front 1049602 6
1.3 anim_human 40100 40138 17 0 0.0 0.0 0.0
1.0 anim_human 45453 45430 18 0 0.0 0.0 0.0

1.3 anim_human 29515 29535 6 0 0.0 0.0 0.0
with disabled ragdolls not that many choices
fall_head_front 1049602 3
1.3 anim_human 40100 40138 17 0 0.0 0.0 0.0

Basically, anything can go as death animation with ragdolls, since the latter kicks in in the end. Most of the results are jerky though because of current ragdoll physics. Those above are the nicest ones
Individual animations are: anim_human 40100 401xx - standard fall backwards on back.
ani_died 16 99 - standard dramatic kneeling forward, for 95x
anim_human 45400 454xx - fall backwards on face (initial non-death one, falling from heavy strike)
anim_human 45453 454xx - kneel and turn, then fall (initial getting up from falling, played backwards)
anim_human 21700 21713 - bend over and collapse, only for ragdolls enabled!
anim_human 24335 24300 - swing forward and collapse, only for ragdolls enabled!
anim_human 29515 29535 - thrust forward and collapse, only for ragdolls enabled!
Remove the ones you dont like if necessary

Don't forget to change animations number in "fall_head_front 1049602 X" "fall_body_back 1026 X" accordingly.
Edit: changed 90x ones to latest version
Edit2: changed 95x to the latest version
Edit3: changed 90x to latest version
Edit4: added individual animations highlights
