Knitting Question

OK, I have a question.

My mother-in-law has a pattern for a really simple hat, that uses doubled worsted yarn, so would go really well with some of the scarves I've made recently. My only niggle is that it's not knit on circular needles, and therefore the pattern calls for a seam once the knitting has been done. Part of the reason for the simplicity is that she works in a school, and teaches some of the children to knit.

My question is, once I've got to the end, instead of binding off and seaming, could I carefully unpick the cast-on row, and then use kitchener stitch to graft those two edges together, thus making a seamless join?

Would that work?

What do you think?

Oh, and while I think of it, I'm thinking of setting up a "men who knit" web/blog ring. If you know of any Men who knit (or, indeed, you are one), direct them here and I'll get the ring set up.
