Did you move from CL because of hiring or another reason? I cannot imagine leaving CL and if I had to, I would go for abcl and then add clojure. Depending on the business that is of course. As long as I don't need to build a 1000s person tech team, I would not move; it's just far faster until you get to a scale where processes take over everything.
Hiring. And honestly the docs and stuff look really dated and I understand why people are a bit put off. At some point you have to modernize the look and feel of the ecosystem. The docs are really detailed though and if it was just me and a few others I would have gone to CL in a heartbeat.
One of my pet peeves on github is with modern ecosystems that people ask after 1 week of no commits 'is this project dead'; we use rocksolid well documented and robust libraries that have basically not been updated for a decade; apparently you dont need to change the api every 2 days completely and introduce breaking changing in minor versions of libraries where the actual thing they have solved hasn't changed since the dawn of computers themselves... Like is the normal in npm libs for github star vying.
And the supposed lack of libraries; sure it happens, but more often it is so easy to roll (99% of npms) that in CL no one would use the CL lib if their was one; faster to roll than search for one.
I agree with the modernisation steps though: need to bring together fairly recent enough industry users and scan their code base for which common lisp functions and libs are used (as for as I see, most practical people use a subset and don't often go look for different ways to do something they might be buried in hyperspec somewhere) and distill that down to a Industry Common Lisp 'spec' and modernise everything related to that.
