From the offense's perspective, I think this only works with less than 2 outs.

The ball becomes dead at the time of interference.

When there is interference, return any runners to the last base touched at the time of the interference.

For this to work for the offense, timing is important. R2 must not interfere until R1 has touched or crossed home.

By rule, I think you score the run.

At a NUS a couple of years ago, I presented a similar scenario to our instructors. KR ruled that the run would score. I'm not sure, but this may have also been included in one of the ASA rules and clarifications articles.
