ELO rating endgames played against engine

Hi

I believe it could be fun to make some kind of game rating available to the members who play on my chess endgame website http://www.chessendgames.com. I guess using the ELO rating system would be the obvious choice here, but I am not absolutely sure, how to figure out the actual rating algorithm. Looking at the ELO rating formula I need the ELO rating of the opponent, which would be the chess engine. This could just be a constant (which would be ~2600). Or alternatively, to make the rating outcome more dynamic, the value of the engine rating could reflect an actual endgame position, that is, if the engine is behind with a rook in the initial endgame position, the engine rating could be reduced to balance thins.

Do you have a meaning about this, then please let me know :)

Cheers
Bo.

A little follow up:

I have implemented a rating system on my website based on elo. However since this rating system is used for chess endgame puzzles only, material imbalance and difficulty of endgame are some of the parameters I use to adjust the elo.
