...uses a 6 volt battery pack.

I guess they are 2/3 AAA batteries.

I will probably try using AAA batteries.
Do you think it will fly?
Thank you.

AAA cells are about 50% larger than 2/3 AAA cells, so my guess is that AAA cells will weight about 50% more than 2/3 AAA cells. (Probably a bit less than 50% more.)
You could test it yourself -- weigh the current pack, then divide by two, then stick that much weight in lead or coins to the center of gravity of the plane. Then try to fly.
And of course AAA cells may not even fit inside the plane ...

I think trying what Doug recommended (add about 3/4 ounce at the CG) is the best and cheapest way to find out.
