No, this is pretty much what you do NOT want, since if Team A is
intimately familiar with Approach X that is going to condition their
approach. You want the teams TOTALLY independent if you're trying to
do something other than have someone 'check the math'. The latter can
be done without having two groups and two approaches, but won't find
some classes of errors.
