I am faced with the same predicament but I already had the rhino. I think going lighter and wearing a face mask like the one below may be viable. But I would still take at least a year off after your surgery. And even with the mask it’s still a risk and your nose could get even worse.
Look into protective face masks. Its one thing to be scared of a hitter as is. You have legitimate reasons to be scared. Google throws out something like this:mueller face mask
You can use an athletic face protector. Should be fine while drilling, but I don't imagine it being effective during sparring with intensity
