Not interested personally, but feel free to put it up! Sounds like some folks could find that useful!
Here goes:
If you want more ores, there's a couple of things you can do.
1. Change the cluster size of all your undesired minerals to cluster_small. Removing them altogether by deleting their environment tag would probably work as well, but it might have unexpected consequences like the measures you've tried yourself. I can sort of vouch for the "cluster_small" way working as expected (I say "sort of" because I have played one fort with those mods so far, and was satisfied with the results, but your mileage may vary).
2. Change the environment of your most desired minerals to all_stone and their size to cluster.
The second step is important in that it positively makes aluminum or gold or whatever you want as common as microcline. Merely getting rid of the useless minerals might not be enough to give you shitloads of ores, as you might end up with only your "layer" stones and a couple of veins or small clusters of the good stuff.
I have since tested this in a couple of forts, and I can now say that it works on ores rather well. I made most of my ores into large clusters, while making everything undesirable occur in small clusters, and a survey using reveal.exe showed there to be more ores than I'd ever know what to do with.
Now, if you
really wanna go over the top, you can make ores occur not in large clusters, but in
layers. This does seem to cause some instability in world-gen and sitefinder, and I have not played a fort with those settings (as getting large clusters is over-the-top enough for me), but it did work when I embarked just to check it out.
