Ok, silly question. Lexx is a sci-fi TV show that ran from 1997-2002. In one episode they used 'approximately 14.2 Quadrillion Quadrillion drones" to basically suck matter away from the star slowly using gravity.

Ive always wondered: Do you think this is possible? Or would such a large mass simple pull the entire star?

If you create an extreme gravitational gradient, you might stretch a star in one direction. But not pull mass out of it, while the rest remains a sphere, like shown in the picture. A small black hole orbiting the star at close range might do something like this, but I'm not sure.

They would both move towards each other and collide, unless there is something that holds the mass against gravity.

Actually, in binary systems where one star is a pulsar or black hole in close mutual orbit, mass is constantly syphoned off in a "string". That's what forms the accretion disk and thus causes the X-ray and gamma signatures.
