More thinking about geometry, stability with a load, heel clearance for panniers etc than low gears (I gear all my bikes low).
I know Royston (Herts.) is 3 hours drive or less now most of the roundabouts are gone from the A1.....
however....what size tourer are you on? ....geometries are all on Spa website, so you can directly compare chainstay length (for heel clearance)
In terms of stability, the steering geometry varies a bit with size on the Elan (due to commercially available carbon forks being 45mm offset)
None of the Elans have less stable steering geometry than Surly's Trucker.
But two or three things......Differences between a Spa steel tourer and a Spa titanium tourer are going to be slight or even marginal. I would say if you are going to run 2 bikes, you should look for a bigger difference between the 2 bikes.
I'm confused over your use for the Elan.....you say you seldom tour "fully loaded" but you're talking about a steel fork for a 4-pannier setup on the Elan?
A steel tourer is always going to have a stiffer back end than a titanium bike.....titanium is less stiff than steel, and there isn't any more room between the chainwheel and the tyre on a titanium bike than there is on a steel bike. Your existing steel tourer with its steel fork will do "fully loaded" .....and rough handling is unlikely to do more than cosmetic damage.
I'm concerned that if you put a steel fork on the Elan, (and the associated big tready tyres, heavy wheels, hub dynamo.....) you will turn a bike that has the potential to be a gazelle into a sort of water buffalo.
My alternative proposal is to keep the Elan set up for what its good for....putting a grin on your face......with the carbon fork, and 32mm slicks or cyclocross tyres. (Theres a picture of me "playing" on this thread
https://forum.cyclinguk.org/viewtopic.php?f=5&t=113501&start=15) Its not a fragile bike, its quite up to commuting, if you want to take the steel tourer off the road so you can service it before you go fully loaded touring. (In fact, through the winter, commuting with discs is an attractive thought) The Elan is well up for lightweight touring, B&B for example, and also the club run or a bit of bridlepathing.
