Putting different wings on FT plans

After my most recent failure with a scaled down FT Bushwacker, I am looking to build another foam board plane with some modifications. I am really quite drawn to the FT Bushwacker, as it is similar in style and performance to my Durafly Tundra (which I am still too afraid to fly/completely destroy), but I know the Bushwacker is more of an intermediate plane with no wing dihedral. I like the wing size and shape of the Simple Storch, or even the dihedral design of the Simple Cub wing. So, my question is: is there any reason why I wouldn't be able to put the Storch wing on the Bushwacker fuselage, or even modify the bushwacker wing to include the same dihedral of the Cub wing?

No, if it fits, it will fly.
Adding dihedral to the Bushwacker also works.

...any adverse effects on flying (like ballooning)...
Hard to say but it's possible. In some of my own designs, I've had to reduce the wing due to adverse effects.

In my own designs, I aim for a wing loading of 10-15 oz/sqft. Planes in that range fly well. If I use a larger wing, say 8 oz/sqft, the plane starts ballooning.

I should add the 10-15 number only works for a "normal" size plane, 40-65" wing. If the plane is smaller, say 20" wing, the wing loading is much lower, 1 to 1.5 oz/sqft.
