You're joking, right?

Briefly, gfortran's front-end (FE) parses source code into
its own black-red tree structures.  These b-r trees are then
converted into the tree-ssa form used by GCC's middle-end.
The inlining you seek to exploit is done during the FE's
b-r tree to tree-ssa conversion.  So, you would have to
convince g++'s FE to either directly produce gfortran's
b-r trees or convert g++'s tree-ssa trees into gfortran's
b-r trees so it can then convert back to tree-ssa form.
I doubt that the g++ developers would be thrilled with
such a hack.
