You may want to consider the via-in-pad as HDI vias (one or two layers deep) otherwise the real-estate gain may not be all that beneficial. Also stubbing of high speed signals may be a concern.

Subject: [TN] Via in pad using filled or plugged vias

We are looking at the possibility of using boards designed with vias in pad and having those vias filled.  What should we be concerned with? ( I know this is a overly broad question, just looking for a place to start.)

Thanks,
