Yes, but implementing it is not easy because so much of Gnus assumes all
the data is in place.  You could, instead, lower the subscription level
for the nnmaildirs to 5 so they don't get checked on startup, and check
them manually with `M-g'.  I realize it's not a good solution but it's
immediately usable.
