But I already knew my "theory" was bogus. If it were right, the sun should have swallowed the earth a long time ago, which is obviously not the case. That is not to say the idea can't work with some adjustments, but that is beside the point - any idea, no matter how preposterous, can work with adjustments.

However, the reason I'm intrigued by the inflating-balloon view of gravity is that it is, at least as far as I can tell, totally analogous with Einstein's accelerated-elevator experiment. Einstein formulated the hypothesis that gravitational mass is the same thing as inertial mass, but even though the hypothesis has been confirmed by experiment, there is no logical basis for it. If gravitational mass is simply "resistance to acceleration", does that mean all objects resting on the surface of the earth are being accelerated a G right now? How?

An inflating earth seems to provide the logic, but it also creates difficulties, as you pointed out. But I can't think of anything else except, perhaps, that gravitational mass is NOT the same as inertial mass. Do you think that is possible?
