Or, dump rubbish into it so the surface cools down. But then of course the inside gets hotter ... not quite a nova by my back-of-an-envelope calculations, more a bloop, but big enough to thoroughly sterilise any planets.

 How much rubbish did it take to make a measurable effect on the Sun's surface temperature? And was the rubbish more like iron or more like chicken bones?
 

Large parts of Uranus's core and mantle, so something in between iron, chicken bones, and water. Anything which was dumped would sink slowly if it's heavier than hydrogen. It would also be less conductive than hydrogen and mess up the conduction cells at the Sun's surface (which is what causes the blurp).
As to why people might want to have dumped dump Uranus's core into the sun 20,000 years before, it was to get the momentum and drive mass to raise Venus into L4; though by that time Mars had been made bigger with more core from  Uranus and moved to L5, so the L naming doesn't really apply - three similar mass planets in a common orbit around the Sun..
and it was mostly done with giant elastic bands .. but that's another story :)
