Personally I wouldn’t mind the post-destiny books slowing down (or even taking a step back) and further exploring the post-Destiny era before getting to the events of 2387.
One of the reasons I love the Star Trek books is you get to see the characters grow over time and given that they have now expended outside of the TV ‘crews’ of the USS Enterprise, Deep Space 9 and USS Voyager to include a wide range of additional crews (USS Titan, USS Aventine, USS Robinson, USS Vesta, USS Galen, USS Demeter, USS Excalibur, USS Trident & USS da Vinci) and interesting characters to explore.
VOY is still at 2382 so have an additional 4-years’ worth of stories to be told before 2387.
TNG & TTN have started new missions at the beginning of 2386 and there are still periods of time post-Destiny which is rarely touched (TNG has a 2-year period from Losing the Peace in 2381 to Plagues of Night/Raise the Dawn in 2383 and TTN has a 3-year period from Fallen Gods in 2382 to The Poisoned Chalice in 2385) that have potential for further stories.
DS9 have just started to explore the crew of the new Deep Space 9 and with Ascendance is just starting to tell the stories of the 4-year gap between The Soul Key in 2377 to Zero Sum Game in 2382. There is also now the USS Robinson’s new mission in the Gamma Quadrant and Julian Bashir on-going ventures with Section 31 that have potential for further stories.
While the USS Aventine has featured in novels post-Destiny, the majority of the period since its launch in 2380 has potential for further stories. Likewise the USS da Vinci made brief cameos in A Singular Destiny & Indistinguishable from Magic however the period between the series end in 2377 is relatively untouched.
It would also be good to see some of the past Star Trek characters of the current era appear (Samir al-Halak, Darya Bat-Levi, Jo Stern, Yuriel Tyvan, Anjad Kodell & Thule G'Dok Glemoor from TLE; Gilaad Ben Zoma, Phigus Simenon, Idun Asmund & Tricia Cadwallader from STA; Morgan Bateson, Miranda Kadohata, Sam Lavelle & Aquiel Uhnari from TNG: Thirishar ch'Thane from DS9; Tillum Drafar & Ayala from VOY; Mackenzie Calhoun, Elizabeth Shelby, Burgoyne, Kat Mueller, Soleta, Zak Kebron, Robin Lefler, Arex Na Eth & Shiboline M'Ress from NF; Sonya Gomez, Domenica Corsi, Mor glasch Tev, Vance Hawkins, Sarjenka & Soloman from SCE; Matt Decker, T'Priell, Edam Astrun, Yoshi Mishima & Kyethn Zund from the SA comics; and Fo Hachesa from TTN) – all of which have potential for further stories/development.
With all of the above (and the on-going stories of DTI, which I have not read yet but is the next series I am about to start) there is potential for years’ worth of novellas and novels without ever having to worry about the impact of dealing with the events of 2387.
