ICE Lagoa simulation over envelope?

[Splin]

Hi,

I got a characters hand which is changing to cloth. The hands animation is done with enveloped bones, it would make sense to add to it just another simulation layer with ice but my test showed that it does not play nice together. Namely I am animating the lagoa effect with constraints, where we see that hand is gradually changing to cloth. That seems to not to work.
What kind of solutions do I have to "bake" the character animation so that I could use controlled lagoa sim a top of it?

ps. I tested mdd baking, that did not work at all.

Thank you!
