Hey this is America and you can do what you want to.
Here's my two cents.
You will likely be 100% fine and will never encouter a problem. I can tell you that things with a BX happen FAST, and the one time you install the FEL without "messing" with the ROPS might be the time you have an issue.
I've posted this previously: I was using a chain in ONE of the bucket hooks to move my <1,000# boat trailer across the yard. (This is before I built a hitch for the bucket.) As I backed up and turned, and I had to raise the FEL a lot to allow the jack stand to clear, the rear roller bolts that stuck down about 8" below the frame HOOKED in the grass and stopped the trailer.
When the chain drew tighter, and with my BX turning, all of a sudden my right rear tire was six inches off the ground! Fortunately, I was in 2WD, so the instant the tire left the ground, the differential kicked in and my rearward and TIPPING progress stopped.
It was a RUDE awakening to me, as all of a sudden, I'm tipping and I don't know why. It was QUICK!
Another time, I was moving a HEAVY trailer loaded with concrete a few feet and needed rear
ballast, since I didn't have anything on the 3PH. I had my son, a football lineman, set onto the lift arms and hold onto the ROPS while I moved it.
He shifted his weight to one side and the rear of the tractor came up! Sure got my attention!
As I said, you'll likely be fine doing the ROPS removal. But things happen fast. And if anyone else but you runs the BX, they might not be as quick on the controlls as you are.
Me, I wouldn't do it. Just be careful.
