  Let Q be any II_1-factor. It is shown that any standard lattice G can be
realized as the standard invariant of a free product of (several) rescalings of
Q. In particular, if Q has fundamental group equal to the positive reals and if
P is the free product of infinitely many copies of Q, then P has subfactors
giving rise to all possible standard invariants. Similarly, given a
II_1-subfactor N of M, it is shown there is a subfactor R of S having the same
standard invariant as N in M but where S, respectively R, is the free product
of M, respectively N, with rescalings of Q.
