What can be done with broken aperture blades?

A friend gave me his A135/f2.8 with broken aperture blades. What can be done with it?

One option is to remove those blades and then the lens is just a fixed aperture lens. What are other possibilities?

Also, any disassembling instructions?

Perhaps remove them, find a copy with damaged glass and frankenlens it?

"Broken" will need some detailing.

Cardboard discs make a simple Waterhouse Stop, I use them on projector lenses that I mount on the K10 and they work just fine. I don't even make a big fuss over how neat I cut the hole, I use a craft knife and just hack the hole bigger until I get a good result, then I make a decent one.
