Before designing your aircraft to carry fuel in the outer wings, here are
a couple of issues to consider:

1) When dealing with the issue of loads on the WAF, you must also
consider the fact that by adding 60 pounds on the longest possible "arm"
from the WAFs, any flexing by the wing will or at least may place
enormous torque loads on the WAFs, possibly more than their design could
withstand. (read - wing failure)

2) Again, adding sixty pounds of "ballast" on the longest possible arm
from the longitudinal axis could greatly complicate spin recovery.
Remember, mass times acceleration equals momentum. It is quite possible
that after a two or three turn spin, you may not have enough rudder
authority to overcome the additional rotational momentum. (read - no spin
recovery)
