....Shimano road triples are 130/74 pcd, so although you can't go smaller than 38 for the middle ring, you can go down to 24t on the granny ring if you can find a front dérailleur to cope.

When you say find a front derailleur that'll cope - I guess you mean that the drop will be so long that you need a big enough cage(?) to move the chain?

I was also thinking, that as cassets are simple to change, that might be an option... although I haven't actually looked into how much they range in ratios.
