I did something vaguely similar under a BGA with VIAs. 

In the footprint editor, when developing a BGA footprint, I placed through hole pads also,
on grid, each nearby a ball pad by the same name.  Then with the proper solder mask
setting, and pad name same as the nearby SMT ball pad, I was able to convert those through
holes effectively into pre-placed vias.

Then during routing you had some help in tying into the something that would help with the
fan out.

Some day it would be nice if the "module editor" could actually edit modules, rather than
mere footprints.  Where module equals the pads and the fan out traces.
