The modified-gyroscope would contain modified generator(s) similar to ones used today for converting mechanical energy into electrical energy.

I've been told moment we tried to take power out of our spinning gyro—by hooking it up to generator or whatever—the apparatus would slow down and then come to a stop . . . because we'd be putting a load on that machine, thus introducing additional frictional, viscous, and other drag forces. The load would act just as it would on a Pelton wheel, a diesel engine, or a steam turbine: it would consume power, tend to decelerate the "engine", and require an additional energy input to keep speed up and prevent the whole system from grinding to a halt.
Would this also be true for a "huge" powerball gyroscope?
How could you conclude that the potential power output is equal to or less than 100% of the input?

all you are doing is using electricity to create angular moment, then hoping that the resulting angular moment will produce more electricity than required to create it, while at the same time overcoming the drag coefficient. Won't work. There is nothing magic about angular momentum. It still involves velocity and mass.
You might look at taking an engineering dynamics class, usually sophomore year, or pick up a calculus based physics class, also sophomore year college level.
Sorry for the bad news

No. As mentioned in a couple of previous answers, you cannot get something for nothing. This law of physics is known as the law of conservation of energy. It states that in a closed system no energy can be created or destroyed. Therefore, you can't just make energy, it must come from somewhere (ie. you must add it into the system). However, energy can be changed into other forms, and that's where "losses" come into play.
If you were to set your gyroscope spinning and leave it alone it would eventually come to a stop due to some of the energy that you put in to make it spin being changed into heat from friction. Friction is the killer of all mechanical systems, and the best we can do is to reduce friction as much as possible. So maybe you could reduce friction so much that your gyroscope spins for a really long time, but it won't spin forever.

Nope. In my humble opinion, the reason gyroscopes figure so often in perpetual motion machines and space drives that defy Newton's third law is that the maths of gyroscopes is difficult to understand. I'm a physics major and I never really understood the gyroscopic effect. The maths was very confusing.

You're talking about a perpetual motion machine. They only exist in science-fiction.
The only time you get more energy out of a system than you put into it, Is with nuclear fission.
Forget the pipe dreams.

Are you trying to make an engine that produces more energy that the one he uses for motion? Don't think it's possible, sounds like the perpetual motion machine. I think it goes against the Physics laws.

no - you dont get something for nothing. you cant get more energy out of something than is put into it.
