Three or four more detectors is definitely not easy. The current ones were built, tuned and retuned over 25 years, and with approximately $1B spending on the US side alone (ignoring efforts in Europe, Japan, Australia, Brazil, Malaysia, etc). There are early plans for new detectors but to surpass the sensitivity of the existing network they will need even larger, more expensive facilities and equipment - unfortunately pushing the boundaries of human understanding is expensive.
