i've always thought sibling wise olivia munn, vanessa hudgens, chloe bennet, or shay mitchell would be a great sister for him. brother wise: keanu reeves (which older), piolo pascual, henry golding, richard gutierrez, paolo montalban, ross butler, manny jacinto, or the more white route with zach quinto, brendon urie, myko olivier, or even matt bomer.
