If the latter overrides the former, than you could tilt vertical while extending up.

Even if both rules apply at once, you might be able to time the rotation angle (RA) and extension length (EL) so that the projection in the plane of the bumpers (EL*sin(RA)) never exceeds 15" outside the frame perimeter (EL has to shrink as RA grows). That's going to be a nightmare to enforce though.
The GDC has already noted elsewhere that the 54" height is robot relative, so as tall as necessary is probably oriented the same way and perpendicular to the extension direction.

Not tipping backwards is the tricky bit for a low bot with a tape measure lift.
