Having moved many adult LMB I can tell you they will tend to lose weight. It seems they do not adapt to a new environment very easily. I have seen fish sitting there with BG almost swimming in and out of their mouth and not feed. I move mine from other locally owned ponds and ponds I own. Best and cheapest alternative is to find someone that has to many bass in your area that would be willing to part with some.
EDIT do not forget that diseases can be moved with fish when doing this.
