high% upward angle.My advice would be to tackle one project at a time.
The urban conversion should be easy to do and the lessons learnt from that project would help on the harder conversion of the InterUrban build.
Usually to determine wh/mile or wh/km we base it on a similar vehicle - but not many bus conversion projects on this site!
So you may have to do the calculations your self. Have a look at determining energy usage doing a roll down test (or also called a coast down test).
Basically get the bus up to speed on a flat road (110 kmph) and time how long to takes to get to 0 kmph in 10 kmph intervals. Then repeat in the other direction. From these timings you can work how much energy is lost to aerodynamics and rolling resistance.
In regards to AC unfortunately there isn't an off the shelf product available at resonable price point to DIYer's. For the interurban it wouldn't help much but would be good for brake assist (down hills, regular stops). So the money better spent on more batteries.
