I seem to remember that the Alter Rebbe writes that if a Yid does a Melacha and has a particular purpose in mind and another Yid wants to have Hanoah from the Melacha in a different manner that it is okay?

There is no such Halacha in Alter Rebbe Shulchan Aruch. You might be confusing this with something similar; There is a Halacha that one may ask a non-Jew to…
