Feature Request: Integration of easter_date()

Jason, thank you for this great piece of code!

Would it, in your estimate, be at all feasible to integrate PHP’s easter_date() in your plugin?

What I’m hoping for is being able to do, say
Palm Sunday = [date format="EE, dd.MM.Y" time="Easter -7 days" relative_to="+2 years" language="de_DE"]

Or can you perhaps think of any way to enable your plugin to accept “date injection” from another source?
There’s another plugin Wpit Easter which uses [easter_date], and I was hoping one could simply do time="[easter_date]" …

Any thoughts on this?
