It seems on the old numbers that me and my wife cannot ride in the front
seat together when fully fueled....

Well, there is "should not" and there is "cannot." Obviously, it is
possible to fly an Arrow with two adults in the front seat with full fuel.
It's done every day, all over the world, safely.

That said, you may be a bit out of CG range -- which is obviously computed
rather conservatively.

Just put a sand bag in the luggage compartment, and you'll discover that
flaring to land is MUCH nicer.
