If you launch a program with /usr/lib/ld-2.25.so /usr/bin/foo right now, that probably already works because it disables the separate base. There's probably a way to get ASan linked executables to disable the separate PIE base automatically, making the exe get mapped with other mmap allocations / libraries.
