Can we make isoglosses?

Personally, I don't see 'h' as a possibility. The two instances of 'h' in 116v have a descender below the right leg: this is common in similar cursive scripts. The second letter in 'b' is closed as the bottom, though the final part of the stroke is faded, it is still visibile. This faded stroke interrupted the darker stroke of the left leg, carrying away some of the ink: the 'h' does not explain the interruption in the left leg.

Overall, this 'b' seems to me to be comparable with that in ubren(?) in the fourth line. Each of the Bs in the page has a different bottom and this variant fits with the others.

Also, does the spelling 'ahia' appear anywhere?
