Yeh, and Ash, says he can get an extra few days off and go on the roadtrip.....

Roads will be snowy, and in places icy. 4wd is nice, but not essential. Proper winter tyres is essential (required by law in Sweden, but a UK registered vehicle *may* be able to get away with not having them). The ideal is studded tyres (such as the excellent but somewhat pricy https://www.nokiantyres.com/winter-tyres/nokian-hakkapeliitta-8/ ), but modern "friction" (non-studded) winter tyres will work too.
As to route choices I suspect that staying on the E4 as long as reasonable will actually be faster than a more inland route shown on the map. but going further inland (e.g. E45 up to Arjeplog, and then making your way NE) would be a real treat for those who have not seen the Swedish inland much. But almost certainly much slower. if you go by way of Arjeplog make sure to stop in the Silver museum (http://silvermuseet.se/). And potentially more moose/reindeer on the road.
You do know it's going to put 4 to 5 days onto the trip for travel time, don't you
