You certainly can reduce the angle, but you need to be very careful and only do it by a minimal amount. I’d first use a very thin shim (say 0.5mm) at the front edge of the pocket and see where that gets you. This should give you a good idea about the angle change required. It should take the bridge down by around 2mm. What you don’t want is to decrease the angle so much that you can’t lower the bridge enough and end up with a high action. A high bridge is preferable! You might consider living with a shim (if it’s not too obvious) as the safe option.
