It’s worth the effort. Many implanted people regret to not be implanted earlier. Hearing aids probably don’t give you over that 68%. The only way to elevate WRS score is cochlear implant.
My decision about my left ear was easy because it hears totally zero. Your left ear is quite unusable to hear speech so you also have almost nothing to lose with surgery.
Concededly, I have CI from Cochlear company, but if you plan use Naida on right ear consider Advanced Bionics because of bilateral cooperation with Naida HA mics:
So, for bilateral (more precisely - bimodal, see my nickname) features it’s worth to think about Naida L90 for right ear (90 instead of 50).
