I checked the code for Graphics`Graphics` and found that,
with UnitScale instead of PiScale, you can get lower divisions
than Pi/2 (PiScale is implemented using UnitScale):

UnitScale[0, Pi, Pi/2, 5]

{0., 0}
{1.5707963267948966, Pi/2}
{3.141592653589793, Pi}

UnitScale[0, Pi, Pi/4, 5]

{0., 0},
{0.7853981633974483, Pi/4},
{1.5707963267948966, Pi/2},
{2.356194490192345, 3 Pi/4},
{3.141592653589793, Pi}

Maybe that's an OK solution?
