And what kind of cord are you going to plug into your beefed up 20 amp

Will your 20 amp trip like a 15 amp?, I think not. I would guess few fires
are caused by the wiring in the walls, rather more likely, a damaged lamp
cord on a breaker that won't trip.

The same thing as will happen with a 15A breaker. An 18 gauge cord with
a short will carry 20A more than long enough to trip the breaker before
it gets hot enough to cause a fire.
