I'm bumping this post again, as a result of the post yesterday about immobilisers from down under.
Today I revisited my immobiliser. In the end, the only way to get the sensor loop close enough to the key fob is to enlarge the hole in the shroud. There's no way of making this pretty. Previously I had reinforced the back of the top section of shroud, because the small screws make a mess of the plastic if you don't take a lot of care. So I've araldited some aluminium sheet behind each screw, and then covered that in leather to stop any chafing of wires.
This image shows my previous attempt at pushing the loop towards the key. The loop is hanging to the left of the lock barrel. This time I repositioned the padding even further out, and enlarged the hole so that the loop protrudes through the cowl.

There's no tidy way of covering the messy result of this, although sometime I may have another go at it. For now, a circle of black leather protects the loop and tidies it up. I used double sided tape, so it can be removed easily should the need arise.

It has worked every time as it should after doing this modification.
