Bournemouth Seventh-Day Adventist Church

I need some suggestions of great type ideas to go with this. The client has decided against the rounded sans type I used in the presentation and would prefer a serif option - looking a bit more traditional.

I can't seem to find something that works – a bit stuck perhaps, and could do with some fresh eyes on this. Any ideas? Am I going to need to amend the mark to be less of a uniform stroke width?
