You can probably gain a little, but (as you've already seen) at the expense of considerably slower post-processing, and quite a bit of extra storage space.
Given that you're shooting with a fairly wide angle lens, if you want more detail you'd probably be better off using a longer lens, and stitching together a panorama instead.
I'd consider drizzle ...
You might also look at Lynkeos (https://lynkeos.sourceforge.io). Although I haven't had a chance to explore its features, I do know it at least launches on macOS 10.15 (unlike some others). I have seen recently published (last month or newer) videos on YouTube where the software was being used to good effect. YMMV.
