Good luck to them, but I can't imagine them getting over 5%. Morgan has some pretty wacky ideas. And he won't be helped with his views on cats - even though he's bang on on that score, it didn't make him popular.
Still - nothing is impossible, but to get over 5% he would have to take such a number from the greens that it would mean either Morgan or greens, but not both. So his big threat will be to Labour/Greens.
