Considering that voters are "supposed" to vote in only genres of their expertise/ only allowed to vote for 15 of the 80 genre categories during the nominating round of voting, I don't think it is at the top of many voters lists for their 15 allowed votes. Add to that even among those with expertise there will be at most 16 Broadway cast albums with a few off-Broadway, and concert recordings, which is likey one of the smallest submission pools for any grammy category. Its not like SITPWG will be trying to grab nominators attention for one of the overall categories, thus as long as its released by the end of September it should be fine.
This is likely why Kinky Boots' west end cast recording was nominated last year, as Lauper and her friends in the industry (of which i assume are many) likely went out of their way add it to one of their 15 nomination ballots, but elected to vote for more competitve categories during the final voting.
This theory would give Dolly and Comet and edge during the nomination round, with DEH as the reigning best musical getting a nom. Then the last 2 spots are very much open, if they decide to fill them.
I do think that Bandstand has a likely chance of being nominated due to its Hamilton connections, that go out of their way to nominated it.
The the final spot I see as a competition among theatrical favorites/legends, altough most of these final products are nothing to build a career on:
A Bronx Tale (Menken)
Ananastasia (Ahrens and Flaherty)
Holiday Inn (Irving Berlin)
Sunday In The Park with George (Sondhiem-clearly the superior, but you never know)
Last but not least is the wildcard of the season that was Come from Away, which could easily replace Sunday or Bandstand.
