German unification with no Bismarck - possible?

[SavoyTruffle]

As we know from OTL, Otto von Bismarck was the master politician whose actions broke German dualism and helped create the German Empire under Prussian hegemony. Whilst I do not exactly subscribe to the Great Man Theory (since it misses underlying societal, technological, or environmental factors often), one cannot deny Bismarck's handiwork on modern Germany and Europe as a whole.

So what happens if we remove Bismarck from the picture? Say he isn't born to begin with, or a girl is born in his stead. With OvB out of the picture, how would the German Question be answered?

Germany`s unification is quite possible without Bismarck, e.g. with a successful revolution of 1848.
But if your PoD is "No Bismarck", then I´m not sure we can say that the failure of 1848 will be butterflied away.
Thus, let´s assume we`re stuck with pretty much the same picture in Germany in the 1850s and 1860s.
Under these conditions, no Bismarck could mean a stronger liberal camp in Prussia. Germany-wise, the countless initiatives for federal reform or unification would doubtlessly continue, and after 1859`s Austrian constitution, they went on without much Austrian participation anyway.
It may well have taken another two or three decades for a German unification to happen, but I doubt that No Bismarck would mean No Germany in the long run.
How a different Germany might look is really completely open, depending on who finally seizes the initiative...
