Eddie's saving grace is the 5 year wait for her ILR. She won't get anything until she is no longer a guest.

Then you have another option, you are not obliged to get the ILR, you could always get her another temporary visa.

What's the cost of that, around 400 quid, divided by 2 that's about the annual cost of the average house insurance.

I think it's good value. ..peace of mind for a further couple of years. By that time if there are any gremlins, they should of surfaced by then.

Just a thought
