Nothing wrong with that, except you have to add separate node names to 
either side of the resistor. Then instead of plotting Ib(Q2) you will plot 
I(R12). The polarity will depend on the orientation of the resistor. This 
is not so bad, except you will have to turn it around to get the flow in 
the direction you want. Or you could simply add a minus sign to the plot to 
get it to the direction you want.

These are simple things, but are part of the huge learning curve in spice. 

This is why I wish people would post working LTspice schematics instead of 
ASCII or hand-drawn schematics that most likely do not function.
