I think Electrum can handle the standard (Mycelium) seed standard too. So it should work that way around... At least that's what I think I used to do (before I bought my Trezor), but why not try it and see what you end up with? If they present the same public address you should be good to go.
Guess I'll give that a try. I'll give an update with the outcome.
Just tried it, Electrum doesn't seem to recognize the seed. Perhaps I'll just put up with Electrum being buggy or I'll might just use both.
