No, that won't work. Unless somebody knows a game that will let you update without returning to the menu first? Don't think one exists...
I have the exact same problem as you, Apoklepz. I am currently looking into a way to flash the PSP through the serial port adapter (look here) but so far nobody seems to know how. Sony tech people apparently flash the system through the serial port, but again, no info on how.
There has to be an easier way to do this. We just need some way of accessing flash0. If there was an exploit within a 1.5 UMD game it would probably be much easier. That's probably the first step to a non-hardware solution to this problem.
But hey, I'm open to hardware if it'll fix it, just not an overly expensive modchip that is too difficult for me to solder. I'd just buy a broken PSP and hope for an older firmware before I did that.
