I also want this, even just $40 (i.e. "2x") would be plenty. The way it is right now, Pro is a tight squeeze but anything else is total overkill and I have no idea how I'd use those extra tokens productively.

You should try using claude as an orchestrator that hands off the actual building to codex models, works really well and you can save some sub usage

Would a plan with daily quota only work for you better? (no monthly/weekly, just daily)

Yep, exactly what I was thinking too…
