Inductive leveling sensor on Delta G2S pro?

[hyperlogos]

I attached an inductive sensor to my G2S pro. There was nowhere wonderful to put it however so it sticks out quite a bit further than the stock level sensor (which I don't have.) My offset as calculated by homing the printer, then moving it to 0,0,2mm and then putting a dime under it, then moving the level sensor over the dime is:

#define X_PROBE_OFFSET_FROM_EXTRUDER 48 // Probe on: -left +right
#define Y_PROBE_OFFSET_FROM_EXTRUDER -14 // Probe on: -front +behind
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.51 // -below (always!)

This is too far. The software does not want to compile with auto level turned on:

#error The X axis probing range is too small to fit all the points defined in AUTO_BED_LEVELING_GRID_POINTS

Is there some way to get auto level to work with the sensor in this position, or do I have to find some way to mount it closer? There is a mount on thingiverse which looks like it would move it closer, but not by very much.
