It's against the natural way, but let's know how your experiment goes Stoney.
As per Tristan, up here with a milder winter it would be a dangerous thing to do, robbing by both bees and wasps is still in full force here at any opportunity. In places like Canada or parts of US with very cold winters it would likely be a death sentence. Maybe SI of NZ has winters somewhere in the middle the bees may be able to survive it.
However I too an an ex Airborne beekeeper, I think Jasper would be spinning in his grave at such a suggestion. We did used to put some honey in the bottom box when wintering, because that was the only place we could take empty combs from to make room, after the bees had arranged the hive with honey at the top, in keeping with their natural urges.
