You may want to consider using a streaming executable approach. An easier solution would be to create a new proccess with no active threads, and manually setup the proccess's pages and resolve the addresses in the IAT(You may be able to avoid this step, I can't remember if there are APIs that will do this for you). You will need to allocate a page for the thread stack and for sections of the executable as well as load all the libraries, and setup the thread's registers accordingly. Either methods take a lot of work. I've created a proccess from a memory buffer, but in new versions of windows this is quite unreliable and unsafe.

It's safer to download the file and execute it using the CreateProcess API, then deleting it when you're finished.
