Sounds like you know plenty about breeding but outcrossing does not improve line breeding its the opposite, it helps relieve the burden of the line breeding by intorducing new genes. Some people who dont know breeding may encourage you but sounds like you have some worthy pairs of pure fish that would be more rewarding to breed. Plus you will be able to rehome them. When you cross two different cichlids you end up with mostly grey ugly things or fish with 1 cool feature and nothing else. If you do get something you like and want to breed it further theres the old fertility issues to deal with. Of course if you really do have the space and time and can deal with growing unknowns out to 2 or 3" and destroying hundreds of fish go for it. It is how we got flowerhorn after all.
What kind of dogs do you breed for hog hunting? Lots of guys in the south using staffies. I have always wanted to hint wild hog.
