Get the full wheel on eBay for £99, which is less than the hub alone on SJS.
Otherwise, if you like complications, the hub measurements are similar give or take a couple of mm so I would say yes.
ACI double butted stainless steel spokes from Cyclebasket start at £0.21 with nipples, so not a great expense to go for new ones.

Thanks all. Looks like it's worth a shot trying to swap the new hub straight in.
I know it's a bit ridiculous to worry about weight with a 1kg hub on a steel bike with front and rear racks and metal mudguards...but still, that pre-built wheel has a 700g rim and I'm guessing it may have plain gauge spokes too...
The hub can be had new for £90 so I'm going to go for that, and either do my best to swap it in or get a bike shop to do it if I mess it up.
Cheers!

I've been running the excellent 3 speed Sturmey Archer SRF 3 on my Pompino for maybe 18 months now, and it's great. I have it so the top and bottom gears are something like 70 and 40 inches.
But it's not enough for me to get up steep hills loaded, at the end of a long day when the paths are muddy or what have you.
So I want to get a 5 speed SRF 5, which should allow me, according to Sheldon, a range of roughly 70 to 30 inches. Not a huge difference for the money, but I reckon it will be enough, and it's a lot cheaper than buying a new bike, and I love my Pompino so I'd rather not have to go derailleur.
Can someone who knows about wheelbuilding tell, from the stats here, if I'll be able to reuse the rim and spokes from my SRF 3 build and just swap in the SRF 5? It would keep the cost of changing hubs down significantly. Both would be 36 hole.
