There is much data that shows that conversion therapy is effective in preventing people from pursuing same-sex attraction.  The APA only recently decided, without evidence but with much political pressure, to classify same-sex attraction as normal.  Previously, it was considered in need of correction.  The same is true of sexual dysphoria.  There is no scientific evidence (e.g., genes) that shows these sexual orientations are innate.  Psychology is a psuedo science, not true science.  It is speculative.  You proposal is purely political.  You have no right to impose, under penalty of the law, your political viewpoint on parents and doctors.  Do not interfere in the relationship between child and parent.
