Answer 1

No, you shouldn't be able to blow the speakers.. a properly designed combo amp is mated with speakers that can take anything the amp can normally deliver. Bass pickups don't deliver any hotter a signal than any other pickups... they're just delivering it an octave lower.

Your probably will really be simple: weak sound. It simply takes more energy to deliver an effective bass sound. As well, your amp's EQ is designed for the range of a standard guitar, same with the speakers. So you simply won't get the sort of reproduction to best represent your bass. In fact, depending on the amp, it's possible you'll actually get less output than you would from the guitar, depending on it's low frequency response.

Now, will this matter? If you're gigging, probably.. a 30-50W guitar amp is probably fine for a small club, but for a bass, you're probably want 150-200W for the same space. For practice, it's probably no big deal.

And you CAN get a usable bass sound. I play a Line 6 Variax, and I usually have a couple of bass models in there, sometimes used along with a phrase looper, so I can lay down a quick and dirty bass line before switching to a normal guitar sound. It works, but though my 30W Roland Cube, really only good for practice or a small room.
