You could always save the offsets in other vars, like #1001..#1009 = 
#5211..#5219 when you touch off.
Then, when you do the G92.1 to reset, just move to 0,0,0 (,0,0,0), and issue
G92 X#1001 Y#1002 Z#1003 (maybe negative, you'd have to experiment)
to restore the original G54 offset.

If you make subroutines for saving and restoring the parameters, it 
would make things very simple.
