Mae'r Gweithgor wedi dod i'r casgliad bod achos dros newid ac mae tri opsiwn wedi bod yn destun craffu rhagarweiniol. Mae rhain yn amrywio o ran maint o ailgyfansoddi'r Comisiwn fel corff modern hyd braich; uno swyddogaethau’r Comisiwn Brenhinol gyda rhai Cadw o fewn Llywodraeth Cymru, ac uno swyddogaethau'r  Comisiwn gyda rhai Cadw mewn corff hyd braich tu allan i Lywodraeth.
The Working Group has concluded that there is a case for change and have subjected three options in particular to preliminary scrutiny.  These ranged in scale from the reconstitution of the Commission as a modernised arms length body; merging the Royal Commission’s functions with those of Cadw within the Welsh Government; and merging the Commission’s functions with those of Cadw into a new body operating at arms length from Government.
