Of course it is, but it would be always snake or always circle... hm making both patterns possible to chose is little hard, it could for example base on heading (even heading number - circle, uneven - snake) or something like that, but this would confuse players that don't read user manuals
And you still could not chose direction of snake after torpedo enters water (only same sa missile is possible, or other fixed setting) so the enemy would know launching sub bearing by observing torpedo course...

I'm a bit bothered that the wire would break at the same time whether the sub was moving in the same direction as the torp as it would if it was moving directly away. There needs to be a way to account for relative motion for this to feel right.

Hm I though I answered that - you can't just drag the long wire through the water, it would break. That's why second spool of wire in torpedo tube was needed. If you could just drag the wire then one spool would be enough, just like in Mk-48... But second spool for sub movement was added. And even common sense says that you can't drag few MILES of thin wire left in the water or laying on the bottom without breaking it... So, with ADCAP it doesn't matter if the sub is moving in the same or the opposite direction, the "center" point of the wire of the wire stays in the water at or close to launch point and both ends are unrolling from spools (one on torpedo, one on the sub). If EITHER of the spools ends, the wire is broken. So if the sub moves more than 5nm in any direction or torpedo moves more than 10nm in any direction.
The UGST is said to have 25km (13.5nm) of wire, but I don't know if it's all in torpedo or how the length is divided between torpedo spool and torpedo tube spool. Anyone knows ? In comparison, the ADCAP would have total of 15nm of wire (10nm in torpedo, 5nm or so on torpedo tube spool). But UGST is much longer torp than ADCAP (7.2m for UGST and only 5.8m for ADCAP) so it's probably possible to fit whole 13.5nm of wire into the torpedo... but that would leave sub with limited maneuver so probably similar two spool system is used on UGST ? It was said somwhere that full length of UGST + "wire coil" is about 8.2m... On a picture of TEST-71 two wire reels are described - internal and external. So UGST most probably use same system too... yes, I just found info that UGST has internal fuel tank wire reel and external left-behing (although described as "towed")wire reel. Even more interesting UGST info:
telecontrol wire, km: torpedo guidance wire reel - up to 25
towed guidance wire reel - up to 5
So 25km (13.5nm) wire in the torpedo and 5km (2.7nm) of wire in torpedo tube. So guided torpedo run 13.5nm, free sub movement after launch 2.7nm. Seems UGST has advantage over ADCAP in guidance wire length :-), probably because it's much longer torp.
Two PDFs about russian torps, can't find them on the net currently:

Torpedo doctrine used in LwAmi 3.x mod merged with ATC mod (so you could try replacing normal LwAmi Torpedo doctrine with it) - but not tested at all !!! so I'm sorry if it doesn't work... but it should :-)
