Ah, there is another option...I did it on my Alpha...

This was a 60T chain ring...bit hard to find in this BCD pattern but they do exist and so do even larger ones if you really want.
As a comparison here it is against a 52T ring:

In order to space it out from the frame enough to clear it I had to run a 3 ring setup with no derailleur. Shifting could still be done manually by hand if needed but most of the time it just stayed on the big ring.
I also helped it out with this 3D printed guide which just prevented it from jumping off when things got bumpy:

I was able to pedal at up to 60kph with this setup.
