You don't just mean a FLOP (financial failurte) but an outright TURKEY. A show that closes after a brief run and loses its entire investment.
Most Broadway turkeys have problematic books, but often the scores are full of delights. (GOLDILOCKS. DEAR WORLD. STEEL PIER.) Most of these would be good candidates for Encores.
Then there are shows that were sadly misunderstood or unappreciated. The original MERRILY WE ROLL ALONG comes to mind, although most of the revisions now in use strengthen the show, I do wish the opening and closing graduation scenes were restored.
Kander and Ebb's THE RINK is one show that could be revived without any changes. Whether audiences would buy it remains to be seen but a recent local production proved that this show has a good, tight and compelling book and some dynamite songs. (The original was not really a turkey: it good good reviews, Tony nominations and lasted 5 months.)
Another show from that season that can work effectively in smaller spaces is BABY. Great score by Shire and Maltby and book that occasionally gets a bit clunky but for the most part works.
But let's face it most Broadway turkeys flopped because no one wanted to see them in the first run.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
