I guess you could - anything is possible given enough time and money spent. But how would you cap that tube off? And where would you put it? IF it ever would leak your engine would have one huge engine vacuum leak (rough idle).
Since our cars do not have an oil dip stick... a top side oil change can not be done. Its not that hard to change the oil from underneath though.
