I suppose it's possible, but it would greatly increase the complexity. 
There's quite a few cases you'd have to handle, off the top of my head, 
at least:

1) Differences of less than a nanosecond
2) Ranges beyond those supported (more than 5 million years in the 
future or past)
3) Offsets with fractional minutes

I wrote home_run so that it would cover all cases for 99% of rubyists. 
For the 1% of rubyists that need features that the current stdlib has 
and that home_run has not, they could still use the old stdlib version 
(which could be moved elsewhere in the standard lib, or made a gem), or 
Tadayoshi Funaba's date2 or date4 libraries 
(http://www.funaba.org/en/ruby.html).
