Idea for DNS Checks?

Given your infrastructure appears capable of handling a high volume of DNS lookups to determine domain availability, would you be interested in expanding this concept to filter based on security-focused DNS servers? A common issue with many malicious domain filter lists is the high rate of false positives. My idea was to validate and categorize these lists by querying them against multiple free public DNS providers (quad9, cloudflare, dns0 eu, etc). For example, a list could first be evaluated using threat detection-specialized DNS servers, followed by DNS providers known for ad-blocking (e.g. controld, etc). Any remaining unmatched entries could then be compiled into a separate "other" filter list.
