I think it would be best to follow industry and make the tool offsets 
availiable to macro use as variables both as read and write.  On the 
controls I have used the offsets start at #2000 or #10000 or #13000.
When the offsets have a length, length wear, radus/dia., and wear values it 
is know as Type II offsets.

When they start a 2000 you only have 200 offsets.
#2001  Length offsets
   |
#2201  Length wear offsets
   |
#2401  Rad/Dia offsets
   |
#2601  Rad/Dia wear offsets

If they start at 10000 you can have 1000 offsets.
#10001  Length offsets
   |
#11001  Length wear offsets
   |
#12000
There is a break here
#16001  Rad/Dia offsets
   |
#17001  Rad/Dia wear offsets
   |
#18000

It should be possible to change an offset from the control while a program 
is running or at least while it is stopped (feed hold or single step), the 
new offset would take effect at least at the next G43/44 for length G41/42 
for radius comp if hot the next block.
