my thinking here is the high speed flow over a perforated surface creating movement in n out of the perforations at any rate would create a highly turbulent area thick enough to be considered a boundary layer without actually being textbook definition of one.

to answer the original posters question the weight reduction probably would not offset the difference in aerodynamics between a flat smoooth panel and a perforated panel of the same parameters.
