Remove one engine and recertify <G>.
Seriously, the certification determines the gross weight and that is what all airtraffic services use. There is no simple way to "short" the system that I can see. You are going to be limited. The P210 is the only alternative that I can think of that would give you the performance of the 337 but........... one engine. The one you really want is the O&N turbine conversion... now that is the "spaceship" for Europe.
