OOP: polyjuice question

[athenal15]

No: HPFGUIDX 65648

I was just wondering what would happen if somebody tried to poljuice
into someone who is a metamorphmagus.

 Do you think they would look like what the metamorhmagus naturally
looks like, or what he/she is looking like at the time?

 Also, do you think that the person would take on the abilties of a
metamorphmagus while they are transformed?
