F-22 – can its ALR-94 ESM detect another F-22's APG-77 LPI radar?

Anybody read or heard anything about whether the F-22’s ALR-94 ESM can detect another F-22’s APG-77 LPI radar at long ranges?

If an ESM that can defeat the APG-77’s LPI feature already exists, what would be tactical implications in a scenario where four non-stealthy fighters with such a capable ESM are pitted against two F-22s?
