What's wrong with taking one out and letting the other spred it's

If it were possible I'd leave them both but amongst a lot of other
light-loving shrubs these are growing in a narrow corridor of a garden
(4 metres) formed by a 3m wall one side and the long wall of the
house on the other.

I've wondered a few times about letting them go and trying to adapt
the garden around them but I'd only do that if I thought the current
approach might kill them. There'd be an additional problem of reduced
light to the house, so I'd probably end up having to take them out
anyway.
