If you allow overnighting, then you can do this on AA.com via the multicity search tool. I specified MAD-LHR, LHR-MIA, MIA-SXM, SXM-CDG in F (with restrictions) on any oneworld carrier.



There are two flights to SXM on weekdays so you can avoid the nightstop if you are happy to sit in the terminal for hours.

You can also go via JFK or DFW or CLT, plenty of scope there.
