G10 L2 P1X1
be functionally equivalent to
#5221=[1]

I think the answer to that is not of itself
See attached test where origin of X was set to 3 and then #5221 set to 0 and a print of #5221 confirmed that value to the terminal, but the offset remained when the program was started
If you messed about with G92, that might have been different

Would the line:
G10 L2 P1X1
be functionally equivalent to
#5221=[1]
No, for many reasons that I can't fully explain.
Why would you want to do that?

my reason is that I would like to set up a Halui command to change the offsets of more than one work coordinate system in one fell swoop. As far as I can tell I can only effect one set of work coordinates in a single line with G10 but using #xxxxx=y, I was hoping I could string together as many as I need on one line. (To for example change the X offset of G54 and G55 in a single command.)
How about writing a sub which contains all the G10 L2 lines that you need and call that sub from halui?

a quick bit of experimentation showed me that if I issued #5221=[1] then changed from g54 to another (g55) then changed back to g54 it seems to work. But only commanding G54 when already using the g54 coordinates doesn't effect the change. I also found that #5221=[1] G10L2P1 does seem to work, but might not help me. since I can not guarantee or predict exactly what coordinate system might be in effect when my Halui command is used.
The developer I asked warned me that if read only had been available when the numbered parameters for coordinate system were created they would have been read only. He also warned about a few other things that I forget. You could read the #linuxcnc-devel logs it you're interested in the exact conversation.
I highly suggest you use G code to change the offsets and as ArcEye suggests use a sub.
