We don't intend to add this no.
Being able to recover your bitcoin, in extremis, from your wallet words is a real life saver.
With Classic support calls we would always ask if the user had made backups. I only ever recall ONE person saying that they had, normally the reply was a deafening silence.
We call it the 'wallet words promise'. As long as you write down your wallet words and keep them safe, you can get your bitcoin back.
Why don't you do like Electrum does? You can not import private keys to a wallet created with seed, however you can import private keys to a seedless wallet. We can easily switch between these two wallets.
Isn't there a 'sweep' option?

2. Someone asked me the other day, "How can MultiBit HD be trusted if it isn't open source?" I was under the impression that MultiBit HD was open source, but it seems like I was incorrect about this?
Thanks!
