Clark,
A quick look at Google Earth shows extending 35 to to the north would put the 17 threshold almost at the western ring route.
Shame about that little neighborhood not to mention the 3 sets of power pylons. Still, it would allow for simultaneous ILS approaches from the north with plenty of offset.
That maintenance taxiway to the south east of MEL almost heads in the right direction though I am not sure what that neighborhood to the west of the freeway would think about a couple of taxiways through there...
Extending 08/26 looks to be more problematic
If that set up was in a couple of other countries I can think of it would have been done already with a lovely big terminal on top of the freeway
