If I set the v2 files to the v metrics of v1.x above, then the only glyph that exceeds those v metrics is Hind-Bold.ttf's dvAnusvara.amI:
$ fontbakery-fix-vertical-metrics.py -a 1055 -d -546 -l 0 *ttf;
$ fontbakery-fix-vertical-metrics.py *ttf.fix;

High Glyphs
Hind-Bold.ttf.fix: dvAnusvara.amI
So I would like to request redesigning the dvAnusvara.amI to be 5 units shorter, so its bbox is 1055 instead of 1060
