*isa= \&UNIVERSAL::isa;

works great for me. I don't even have to "use UNIVERSAL" for this. There being no UNIVERSAL->import() makes some sense to me, but, as noted in Universally unimportant and overused, UNIVERSAL->import() appears to exist (and causes problems).

Defining a special UNIVERSAL::isa() that can detect when it has been misused would be an acceptable compromise to me.
