Is this combination reasonable to pull with some lubricant? Or should I plan
some "pull boxes" in this run?

Thanks,
you shouldn't need lube and if it's that tight then
your not using large enough EMT.
also, you are allowed a total of 360 deg bends in the
pipe.
NE book states no more than 4 bends at 90 degree's
each.
if your going to use access elbows/pull elbows then you
surely don't need lube.
