Hi, I'm unable to edit the Foam shader, but I have a suggestion, try this if you're interested.
Using 1 Alpha + Life time info as threshold (0-1) will result in dissolve effect
If you can change the foam shader into this, we can have 5x-10x bigger foam, more coverage and dissolve effect over time with lesser foam count.
I've pack a texture that have parabol for main alpha ® + foam alpha circle (G) + foam alpha directional (B) as dissolve step.
The texture is made in Substance Designer, is free to pack into the final Obi package if you want.

If you can pass the foam movement direction as UV, can use the B channel, else can use G channel.
