Hi, about vias, some PCB houses have special technique for vias in a pad
(VIP for short). Look up on YT how it's done. Here is one of results from
quick search https://www.pcbcart.com/pcb-capability/via-in-pad.html

After thinking about it a bit more, what about a blind via?  They can even
be filled with copper by the board house.  I'm assuming this is a 6-ish
layer board, yea?

Since you didn't mention that it was blind or otherwise, i'm assuming you
have regular-old normal vias, probably non-tented?  A blind via will by the
very physics and geometry wick away less solder, because it takes up less
volume.  And if it's filled with copper or whatever the board house can
fill them with, it will take up no solder at all.

See 'A', 'B', and 'C' on the (GASP!) imgur link.  http://imgur.com/a/L0lmS

Would this work?
