DRz400s radiator on a 400E??

I had a bit of a heavy tumble on my 04 400E on saturday resulting in a ruined left hand rad. I phoned a suzuki dealer for the price of replacement and was quoted £240, which is about double what I was expecting.
Anyway, I doubt I'll be able to find a decent secondhand E model rad (most tend to get bent up), but I have seen one of an S on Ebay for sensible money.
It seems I can plumb the left hand S rad in series with the right hand E rad, blanking off the extra bottom outlet on the right hand rad. This should get the bike up and running again until I can get a matching pair secondhand.
Has anybody run S model rads on an E?? I may go for the full S model conversion anyway as I'm planninng to take the bike down to Morocco and like the idea of the option of adding a warning light and fan to the cooling system.

I don't think there is any diffrance between the E and the S model radiators. There is a plug on the E model where the heat sensor plugs in that controls the fan.

The plumbing on the 2 models is quite different hence my question. The E model has 3 outlets on each rad - the rads are cross connected at the top and the bottom, plus the inlet and outlet hoses. On the S and SM the rads are connected in series, so there's only 2 pipes on each one.
Anyway, I've located a pair of 400S radiators plus a set of pipes, so I'll be able to swap the whole lot over. I may need to get the thermostat housing off an S as well, but I'll have a play around with the pipes first to see if I can get around it.
On the plus side I'll now have the option to fit a fan and warning light to the cooling system which will be useful for hotter climates.
