Deleted/Expired domain API - I need a register solution that works extremely fast!

I'm looking for a creative way that will let me register deleting domains that expire every day at x time. The bigger drop catchers have their own way of registering domains before anyone else do, right as they expire - and I want to compete at some sort of level there. My initial thought would be that there might be a way to utilize a list of registrar API's. Dynadot, namecheap, etc etc. Run them in a curl script that would enable us to hit each API every 1 seconds or the minimum time the particular API allows you to. If I had say 20 API's that allow us to register domains and I had 10 domains that I wanted to register that expire at 2PM GMT.. Could I utilize those 20 APi's to hit those 10 domains consistently over and over, let's say each API only allows 1 request/sec. That would mean each domain is being checked twice per second across the APi's *roughly*. Giving us a 500 m/s check rate. If that's the case, we could create 5 accounts at each API registrar and have 100 API's across 20 different domain registrars hitting each domain once per second and rotating through the list. This would mean we drop the check time down to once every 100 milliseconds. Is this a theory that would actually work consistently with what I need? I'm looking for feedback on a solution that I can get custom coded/developed. Looking for someone to create a solution for me :)
