I am all for homebrewing monsters (or tweaking it a bit ). It is done all the time on tabletop games. It would be great if they provide a reason why the spectator never uses petrify (temporary condition, an injury or illness?) but I would not say it is a really bad idea. I liked the encounter.

"When the spectator has fulfilled its service, it is free to do as it pleases. Many take residence in the places they previously guarded, especially if their summoners died. With the spectator's loss of purpose, the flickers of madness it displayed during its servitude flourish" Quote from the D&D 5e Monster Manual.
