At least for me, newer camera bodies have great low light performance, making the need of f1.4 primes for low light situation less frequent unless you absolutely need the shallow DOF, bearing in mind that focus imprecisions are more forgiving at f2.8 than at f1.4. at ISO 16000 unless you need to freeze action with high shutter speed f2.8 is widely enough modren camera bodies almost all offer very usable ISO 16000 or even higher , if you are shooting RAW, with some new noise reduction software like DXO deep prime you can gain as much as the equivalent of using 2-3 f stops less of ISO.
Maybe it's time to invest in a a new body, Canon R6 comes to mind first
I attached a photo taken at ISO 16000 EOSRP that isn't the best for noise control but still good enough, then noise reduction was applied via DXO pure RAW, note this is a 100% crop
