My Easter Sunday ('depleted choir' Sunday) go-to piece is an arrangement over at St. James Music Press (sjmp.com) called "This is the Day", an SAB Mozart arrangement. Not hard and very fitting. It does require accompaniment, though.
Canadash, if your ladies have a hard time with the crossing voices at the end, shoot me an e-mail and I will e-mail you my alteration that deals with that problem (my rural-home-parish ladies simply could not get that spot and it wasn't worth the effort!)
Also, most of the pieces in Ravanello's Secunda Anthologia Vocalis work quite well SAB instead of SSA or TBarB. I have been transcribing them into a S-SorA-AorT/Bar format with a reduction, if you are interested.
Not CPDL, but I recommend "Surrexit Christus" (Pergolesi, arr. Proulx) from GIA. Very effective, optional brass parts, and not too difficult for choir.
I have done a very simple fa-burden version of Ubi caritas which goes very well, and has become a favourite of my little Schola (7 women and one other man). I am happy to send it to you - or anyone on the list - to use in the liturgy.
