Enlarging the hole on that lensboard? Are you guys kidding. Thats going to leave him with a little ring of 5mm of metal. I would not recommend destroying your only lensboard. Look for a 25.5 mm x 0.5 lens. Also, some types of hazyness DO clean off. I'd not give up on that lens you have until I had disassembled it and tried cleaning all the surfaces. If the haze is going to come off, it will come off very easily. If it does not come off easy, then the glass or coating has been etched by the fungus and its not going to get any better with cleaning.
Here are some new lenses in M25 (expensive, but just an example of what to look for)
Here is one for $35:
