Do not let yourself be limited by what is conventional 'normal' wisdom.
Of course a 16x20" print can be had from 35mm negs. You can make 30x40" prints too!
Will they look good? You be the judge of that, not everybody else. It is true, though, that some enlarger lenses will disappoint beyond 16x20", but do not let that stop you.
Like I said, you don't look at a 16 x20 print with a magnifying glass. Jump in , the water's lovely. Have a go.
