A copy of the LDA is available to the submitted batch process, 
so this part of your plan is certainly doable.

Although this seems clearer to me, I still don't believe
your "screen file" portion of the plan will work.  

I have never seen an interactive program run in batch that 
accesses a display file which has *not* been acquired or 
attached to a device.  

If this were possible, then all of the third-party solutions
to convert interactive workload to batch (to avoid the 
interactive tax) would not be making any money since 
everyone would be able to roll their own solution :)

I would love to have somebody prove me wrong here.... or
maybe I still misunderstood what your trying to do with
respect to the "screen file"...
