Is it possible to add an additional dynamic DNS?

I have written a private one (that can be used on my DNS server (and plan to open source it).

It uses bind, Apache, MySQL and shell scripts (Current to-do is to omit Apache and MySQL, making the server side dependent only on DNS server of choice).

The client is simple - cron checking if IP on local interface is the same as resolved IP (from hostname). If so - post to url with several parameters (device id, and device key defined on the server)

If a router would act as a client, cron could be omitted, and a trigger could be acquiring IP on interface.

The server side handles the rest (checking device id and key, updating the IP record, and then updating and reloading the dns zone file).

Required input parameters to be inputted in the router are:
post_url

device_id
device_key

fqdn (if triggered by ip acquired, than it is not needed)

Would You be open to something like this, and what conditions would have to be met, in order to make this a reality?
