I have not gone lower (or wanted to), but I bet you could and still have decent shifting. The little half click positions were adequate for trimming. Granted I kind of don't see the point of indexing in the front, but I have not found it to be a real problem either.
BTW, if you go with lower gearing across all three rings you may benefit from adjusting the FD lower. I think some folks complaint of poor shifting with small rings is because they didn't get that adjustment right.
I swapped a 30/42/52 130/74mm for a 22/32/42 104/64mm and the brifters and road FD shift it fine. I did have to adjust the FD lower.
