I'll second what other people are saying, this is not going to yield good results. My team used a large lead screw attached directly to a CIM last year to lift our ball holder into the air, and it performed very poorly. If you absolutely have to do this I recommend using more motors geared down some, and making absolutely sure that you leadscrew is fully supported on either end. There is limit for the length of unsupported rod you can have in a system that is based on the size of the rod itself.
I don't think that a leadscrew powered elevator (or whatever you are planning) is a bad idea, just that there are a lot of concerns when using leadscrews that are easy to overlook.
