This should be fine.  We do something similar in fem_system_ex4.

You'll understand that error better if you look at the line number or
the full stack trace to get context.

You'll need separate quadrature rules incidentally, because you'll
need separate FE objects (note that they're templated around element
dimension) and each FE object will need its own quadrature rule.

You can test Elem::dim() for each.
