I was thinking of 1300mAh with diodes in series, will that be sufficient for ignition for max 5 flights of 10mins?
Where else can the model lose weight?

You're over thinking it.
The weight is FINE as is, don't screw with that any more.
Instead learn to land with a bit more throttle.
I teach students to fly the plane high and keep bringing the throttle back SLOWLY as they fly until they find the point that the plane will begin to no longer fly level no matter what you do with the elevator, and rather decends in a controlled manner.
That's the throttle setting you want to use until the plane is just inches over the runway. Once it's less than a foot above the runway, you chop the throttle completely while holding it as level as you can, and it will decend and land by itself.
It is so low at this point that tip stalls or regular stalls are merely "landings".
