I think you'll be disappointed with the mag2400, if it can reach that high at all. The Danner is rated at 22.5' which is just a the limit considering plumbing, etc.
I think you are going to be better off with an external pump. Not sure what the Iwaki 55RLT (or the similar Panworld) is rated. An Iwaki 70RLT is rated at 32ft and the 100RLT at 39ft. Both might be slightly overkill. However, anything less and I fear you'll get a trickle, if anything at that height.
