While the pros sound promising this is a real strong con.
Especially as this would mean that 2.4 would not work with OpenSSL < 1.0.
The problem I see is that if you want to use other OS provided libraries
like openldap they have dependencies on the OS provided OpenSSL and
binding Apache against a different OpenSSL version as these libraries
are bound against looks like a big problem if Apache is bound to them
as well.
And building a whole stack of dependencies for Apache seems to be a too
large hurdle for me for adoption.

So currently I would be -1 (vote not veto) on this.
