You may be able to get a hybrid by stripping the eggs and sperm, but no one would go through the trouble of making a cheaper asian arowana. Asians can all interbreed, as they are all the same species, which was recently split into four different species.
I think it would be cool tho. Have the look of the silver with chili red or gold would be awesome. To think some asian people spend fortune to set up a huge tank with super asian aro, would fork out some money to make something uniq and cool.
