Matt has a point in that you're asking for an opinion on something no-one has tried yet.
The actual pro/cons on lace & skin are well documented, so that doesn't need rehashing.
But no-one has the experience to advise you on the combos you're suggesting.

The new ultra thin skins have a limited density.
Is this lower density suitable for you?
Also, the limited density is because of the skin's delicacy.
Do you even know if it can be combined with another material, especially as the lower density may make the join more visible?

Re your perceived demise of this forum, you're probably right as forums are now the dinosaurs of social media.
