It would be great if you could figure out a way to move these to the heap.
I have done a lot of research, and there is no realistic way to increase
the stack size for Java on Windows. The only way it can be done is to use
a binary editor to edit the EXE.

If the memory you mentioned cannot be allocated from the heap, a frequent
suggestion I saw was to start a new thread/process and run the code in
that. These suggestions were assuming there was a way to control the stack
size of that new thread/process. I have no idea if this is feasible, but
it might be an alternative.
