Clearly, all the data to do so is there in the database - and I seem to recall that there exists an extension that will allow you to use the parser in that way - but the Foundation projects do not have such an extension installed and cannot be convinced to render a page for you that would accurately show what ELs it might have had at a given date.
That would be the Memento [1] extension. I'm not sure this is even theoretically possible - the parser has changed over time and old templates might not work anymore.
Your best bet is probably to find some old dumps. (Kiwix [2] maybe? I don't know if they preserve templates.)
