Most people here call 1/4 steps " safe". Anything above is just for noise reduction.
My personal gut feeling tells me, that once the initial inertia problems are overcome, the position accuracy is pretty good. ( With reasonable low acceleration and deceleration ).
So I don't see a problem with 2.5 full steps. As long as you don't try to lift the bed by 0.5 steps only, it should work.
Just my 2 cents

Even on an i3 style printer why not consider a belt driven axis like this one [www.thingiverse.com] but upside down, running up the frame and across the top then down, then you've got 1 motor not 2 and good precision especially with 0.9 degree motor.

Lapping the threaded rods makes them look pretty up close, but it doesn't straighten the rod which is the main problem with using threaded rods instead of lead screws. It's like my grandmother in Tennessee used to say: "you can't make a silk purse out of a sow's ear". Threaded rods are the sow's ears of 3D printing.
