As I mentioned before, yes. I believe this maneuver should tangle both parties until either:
a) Defending party makes the save.
or
b) The attacking party takes off their cloak.
As for the formula on how escape artist fits in:
4+Escape Artist vs DC, fails if your escape artist is lower than the DC. It seems Escape Artist already has this handled. The DC is, as mentioned in the opener, 10+1/2 Attacker's BAB. Maybe with some bonus for every point of deflection AC present on the cloak, if that is possible to code in.

(1] Your attached to the cloak to. Infact dangerously so, its like being tied together, but yours end is around your neck. By game rules this would be Grappling, you would need a str test vs the opponent or this goes bad for you.
(2] Why cant a guy with 30 str just tear your cloak from your body, and your head off for that matter? Or better yet, pull you in and pummel you to death? We all have seen the movies where a guy throws a chain around a bad dude, but the bad dude is so big he pulls the hero in and makes him into pizza.
(3] What happens if you throw your cloak on a person with some sort of flaming ward around them, did you just destroy your cloak? In case of a magic cloak, whats the chances the item now explodes around your neck.
(4] Blade Barrier, shouldn't that just shred the cloak?
I can go on with lists of what if's and thoughts. In my view Anime Science does not belong in Dungeons and Dragons, and where this has been depicted in other media the world lacks magics, super men, and never benefited the hero for but a brief second and rarely resulted in direct victory, more a get away.
1. By which game? PnP D&D 3.5 or NWN2 BGTSCC? We don't have those mechanics in our medium (NWN2), and the suggestion does not suggest them in it. It suggests a much more feasible system, rather. Strength could, however, play a role in the DC of the check.
2. Because, again. We don't have those mechanics in our chosen medium for BGTSCC, NWN2. That being said, our RP is not entierly mechanics dependant. We can do a few things with rolls, though they are not enforcable without a DM present (that said, most will play along. I've never had a situation where someone doesn't.). So, to address that. . .you can already do that, with a variety of rolls.
3. The same thing that happens when you cast fireball near yourself. Nothing to your cloak! (or any of your other items)
4. We can already test this in game, by getting hit with a blade barrier. It doesn't shred your cloak.
