but electric field inside of the (long) spark channel may be as weak
as 300v/cm, and even smaller - it is enough for successful acceleration?

I think that the timimg problem already mentioned is a more serious
objection against this idea (when the air expands away violently the
maximum current already passed). The electric field in the channel may be
very irregular (for example when the spark is forming and when it is
ending), and at some points may exceed by large amounts the average value.
