Wow, you don't have much door left there. Looks like the top is gone, too.
I too thought the wing windows could be removed, but haven't investigated, because I plan on keeping mine.
It looks like 47-50 window regulators are different than 51 and later, looking on Jim Carter's website. I don't know if the earlier regulators (either are available as repops) will fit in later doors though.
[on edit] You were posting about the chop before I finished. That would explain the top of the door cut.
