...as long as we don`t get in trouble to remove the lace from the PSB it sounds like a good idea.
Of course the idea of a "2-Layer" base is against the trend of getting thinner & thinner, but who really needs this ?
Still having troubles with breaking glues & migration into hair and along skin - tested several so far:

1) oli resistant white glue
2) stixxon
3) Basebond
4) walker safe grip

So your idea sounds very welcome for me to think about. Thanks for sharing that with us.

Courious, what BA will reply regarding the availability of a naked & customized PSB.
