toplace can definitely do a vacuum system with lace edges....but it seems to me that the lace would elimate the actual vacuum. not sure though as I haven't tried it.
but yes, toplace will make anything you want....you design it, they can make it .
I would do the vacuum system with a 2" lace front ...that seems like it would be the best choice, but the lace will not vacuum to your scalp, you would need to glue or tape that small 2" frontal area.
