Advice sought on 'easier' choral works for a new community orchestra

Hi, we are a Community Orchestra formed last September (2015) with about 25 regular players. We have already given one or two concerts and would like to put on a joint Christmas concert with a local community choir (established about 5 years ago). We would really appreciate any advice on suitable choral works that are at the easier end of the scale for the orchestra but which are still 'audience friendly'! In common I think with many new orchestras we have a fairly full compliment of wind players, but could do with a few more string players.

VW's Fantasia on Christmas Carols (though there's some potentially tricky time signature swapping towards the end)?
