Blimey! you only want the moon AND the stars!...ha ha
TBH I think the only way would be to play around with weapons' bgl DP misc data i.e.
[MISC_DATA]
unit_family=4
category=37
max_weight=700
weapon_type=9
Here's some info:-
unit_family=
1 - Fighter (default)
2 - Bomber
3 - Ground vehicle
4 - Static object
5 - Ship or Boat
7 - Aircraft Carrier
Category=
1 - aircraft fighter
2 - aircraft level bomber (B-24, He-111)
3 - aircraft dive bomber (Stuka, Dauntless, Val)
4 - aircraft torpedo bomber (Avenger, TBF)
5 - aircraft tactical bomber (A-20, Ju-88)
6 - aircraft strike (Fw-190F2, A-4; 2-engine nightfighters?)
7 - aircraft civil
8 - aircraft recon (Storch)
9 - aircraft transport (C-47)
10 - aircraft fighter-bomber (any fighter equipped with bombs) or Dive Bombers
13 - Cruiser/Aircraft Carrier
14 - Cruiser
15 - Destroyer
16 - Submarine
17 - Battleship
18 - Gunboat/Torp Boat/Auxiliary
19 - Transport/Tanker/Cargo
24 - Landing Craft
21 - tracked vehicle
22 - wheeled vehicle
23 - train car
24 - amphibious vehicle
29 - artillery static
30 - mechanical equipment
31 - structure static
32 - factory
33 - non-target object
34 – runway
Weapon_type=1 (small bomb) - 30lb, 100lb, 250lb, 30kg, 60kg all uses the small FX.
Weapon_type=2 (medium bomb) - 500lb, 250kg uses the medium FX.
Weapon_type=3 (large bomb) - 1000lbm 2000lb, 800kg uses the large FX.
Weapon_type=4 (large bomb, same as above)
Weapon_type=5 (rocket)
Weapon_type=6 (rocket)
Weapon_type=7 (rocket)
Weapon_type=8 (timed rocket) - 8 seconds
Weapon_type=9 (torpedo) - MK13, seems to be for lighter torps.
Weapon_type=10 (torpedo) - Type91, seems to be for heavier torps.
Weapon_type=11 (???)
Weapon_type=12 (???)
Weapon_type=13 (???)
Weapon_type=14 (???)
Weapon_type=15 (Tank) - Jap 330litre, Jap 200litre, corsair/hellcat/lightning tanks, most picked.
Weapon_type=16 (Tank) - US 200 gallon.
Weapon_type=17 (Tank) - US 150 gallon.
Weapon_type=18 (???)
Weapon_type=19 (???)
Weapon_type=20 (Pylons, Pods, Parts) Used for rocket pods, various pylons and SID pilot.
I looked about for a full list but no go, if anyone seeing this post can help?
I think making it a bomb rather than a torpedo, and making it very heavy might give the effect of being carried and dropped from a horizontal position and then goes vertical, entering the water verically, as an aerial launched mine would act. No parachute but acts like it has one. I think playing with weapon 'misc data' may give a better profile(?).
I thought someone had done some working parachutist for a CFS2 Ju52, I think it was Pierino Primavesi who did a Fs2002 Ju52 with parachutists, and that's with a parachutist mdl and a Fs2002 effect.
Talking of mdls, you could make one as an mdl. Mauro Giacomazzi did his pilot as one. Being another ac you can then make it do what you want, animation-wise, including a parachute, but it becomes another ac in the ac listing.
Be good to get a full listing of weapon data.....
