making an 11-30 would be particularly taxing in this instance because 30 and 34 are riveted to the same spider.
Cheers for the EV tip. It would be to make an 11-30. The picture on CRC and ^ @hamrack's video makes it look like it is just riveted together. Hopefully riveted and not pins pressed in. I don't think it would be a problem to drill them out, except maybe for the fact that the 34 on the back looks like it's offset or recessed.

Shimano knows. Look up the EV for any cassette you're interested in by googling, e.g. "CS-HG500 EV PDF"
This shows the eight largest sprockets on the 11-34 are more or less permanently joined together. Making a 9-speed 13-34 would be easy, making an 11-30 would be particularly taxing in this instance because 30 and 34 are riveted to the same spider.
