Right. Lisp totally outshines every other language at building DSLs, so if you reconceptualize your project as a bunch of DSLs that utilize one another, you win big with lisp.
What I'm finding is that I can effectively do the same with a statically-typed functional language. The worst are DSLs with poor grammar and concept-fit which add-to rather than solve problems. The ways in which Lisp doesn't scale (people-wise) are well known and relate to each application essentially being its own programming language.

Well, memes about Lisp not scaling people-wise are well-known on forums like HN.
The actual data on this is lacking, like reports about someone having actually gathered five hundred Lisp developers onto one project and failed.
> each application essentially being its own programming language
Meme-fueled nonsense, I'm afraid.
Every complex application in any language is its own programming language.
New types and functions introduce new syntax, just like macros, along with new semantics.
So you know C? Okay, what's this, from the Linux kernel?
struct usb_host_endpoint {
struct usb_endpoint_descriptor desc;
struct usb_ss_ep_comp_descriptor ss_ep_comp;
struct usb_ssp_isoc_ep_comp_descriptor ssp_isoc_ep_comp;
struct list_head urb_list;
void *hcpriv;
struct ep_device *ep_dev;
unsigned char *extra;
int extralen;
int enabled;
int streams;
};
When and where is this allocated? What does it represent? How do you use it?
Guess what, this is new syntax. No, wait, what, it's just using the regular C grammar, right? How can it be new syntax? The same way that a Lisp program have new syntax if continues to be made out of parentheses, symbols, strings, numbers that conform to a rigid grammar.
The new syntax is in the schemas built with the definition abilities provided in the underlying fixed grammar.
Perhaps less well known are the well-meaning explorations into why isn't Lisp more popular. The absence of a 500 Lisp developers on one project is itself the datapoint being discussed.
The absence of that is because it would require a substantial global recruitment and relocation effort to get that many Lispers into one organization. It speaks nothing to their ability or inability to co-operate on a project.
The vast majority of all software tech ever invented is unpopular today. If we just pick a tech stack, language, editor, OS or anything from the last 70 years at random, it's almost certainly unpopular. That's our first-order effect that forms the bulk of the rational explanation for why anything is unpopular. By definition, not everything can be popular: popularity is the selection of a very small number of artifacts (almost always chronologically recent) to the exclusion of everything else.
The challenge to that prior is that there is substantial overlap in the features and capabilities that were in, say Commmon Lisp a long time ago and yet there was a substantial delay in those features being accumulated in other languages with vastly greater adoption to this point (like Java, although that example might be disingenuous since the releases of Java and CLOS were only a year apart...)
Likewise during the last seventy years some languages saw wild uptakes in popularity for some languages much later in their life-cycle. Who would have expected the modern successes of Ruby?
