Think of the problem in reverse: start with an empty field- the "win" state- and play it backwards, with shrapnel coalescing into bubbles, sometimes leaving bubbles at the shrapnel source. By tweaking the rules-in-reverse, you can generate different levels of complexity.

I haven't thought it through in your particular case, just hope it gives you new ideas.
