Projection attachments like the Dedolight DP1 and the Godos SA-P have kob which lets you tilt the front of the projector to correct the distortion in cases like this.

DP-1 cannot be tilted. A perfectly circular spotlight when hitting the b/g at an angle can be achieved with an elliptical gobo although the focal plane will not fall correctly for sharp edges all around. DOF can be increased by pulling the fixture way back but illumination efficiency will suffer the inverse-square law.

Inverse square law does not apply to focused or collimated light!
