You can import it if you specify bip39 like the OP has.
You can import it but it won't work properly. MBHD uses the derivation path of m/0'/0 to generate addresses (m/0'/1 for change addresses). Electrum uses the BIP44 standard derivation paths of m/44'/0'/0'/0 and m/44'/0'/0'/1
My bad. You are absolutely right. I was going by what I read in this file linked here:
https://bitcointalk.org/index.php?topic=1000544.0 so I thought multibit HD used bip44.
Electrum's derivation path for it's native seeds is given
here but for bip39 seeds it is indeed bip44.
So OP you are going to have to send the bitcoins from multibit to an address in your electrum wallet using multibit HD.
