Near expiration, if it looks like it will get assigned, I plan to buy BRK (on margin) a couple of days before and let that new lot get delivered.

No need to pay a few days of margin interest. You can buy the shares on the day you are assigned and deliver THOSE shares immediately (next day settlement). Then you only pay one day of margin interest.
Even simpler is just to buy back the calls you wrote. There is no need to own that particular block of stock even momentarily.
Presumably you'll realize a loss on closing them, but that's true either way, and offset by the fact that you have been owning the stock that went up, and/or you simply write more calls at a higher strike and later date. No stock goes straight up forever : )
