I want to put one product in a different theme

I am using the Bazar theme and it works perfectly EXCEPT for one product (using the Fancy Product Designer plugin) because when you design your product then click ‘add to cart’, it doesn’t actually add the new design to the cart – this is due to the theme.

I have tested this with Mystile activated and it worked perfectly, it added the user-made design to the cart.

So, my question is, is there a way to continue using the Bazar theme, but put my Fancy Product Designer in another theme or just anywhere else where the theme won’t interfere with adding the product to the cart? So all the products except that one would be in Bazar.
