Mmm... maybe. The problem with the 0.5mm pitch is, you can't get vias or traces between balls on 6/6 trace/space specs. I'll investigate this at the same time as doing the HX routing - 0.8mm parts have similar-but-not-the-same problems, so seeing what we need to do will help us figure out what it'll cost us to do the optional stuff.

@awygle Do you remember what was your conclusion? Looking at the package, some B and G balls do present an issue...

We don't have any margin for two-row escape routing on 0.8 mm with 5/5 rules already, so this is not viable.
