Not really. The slight excess is fuel which will be burnt off. before
landing time. Remember the structure is stressed to much higher G
than 1.015 and if you just slapped a bigger engine in the MTOW would
be increased to as much as 2500. What is dangerous is the position of
the COG and the reduced climb. Make sure you do a weight and COG calc.
for the trip. I can tell you that you should probably expect a more
tail heavy feel than you are used to which will promote a tendency to
rotate too early. Just raise your Vx by 5k and she'll be fine. Your
climb will be reduced to (say) about 400 fpm at 2000' (if I remember
correctly). Don't crash it or you will be in real trouble :-0

Actually, your tongue-in-cheek comment raises a good point. Operating
over gross may well void your insurance. So, question to the OP: do you
really want to make a flight with no insurance in force? Even a small
mishap that gets investigated may well result in your insurance company
abandoning you when you need them most. I'd read my policy carefully
before making this flight just to be sure.
