modifying a MDR?

So I found this merc relay on sale at a surplus place. It happens to be a 3 pole style unit.

My need for these is typically double pole, or sometimes single pole. Does anybody know if it is feasible to re-configure one by removing one or more of the individual relay components? Obviously, the jumper bar connection would have to modified, but otherwise I am not seeing an obvious reason why this couldn't be done. It looks like the three relay barrels are simply tethered together by a tight band strap, which fastens to the mounting bracket.

Any advice?

years back, I bought surplus MDR's from Brad Shute that he picked up at Corning Glass. Consistently, they checked out totally when they were brought up to service levels. While it may not have to directly do with what you are doing, I offer this up as simply cautionary advice.

I still have them since I'm too stupid to throw stuff out.

Why modify? Just use the two legs and ignore the third.

True. That occurred to me, but I was thinking that by splitting it apart, it would be like getting one or two extra devices out of the deal. Tantamount to the Hamburger Helper of the relay world!
