That's my idea actually, as of now small channels are not viable, but they might be in the future, counting on that Bitcoin's value rises ad that people start using AMP/MMP to make payments.

About heavy rebalance strategy, you're right, it doesn't work that well, but the more channels I have, the better it works. Also the payments are doing the lords work here and help me rebalance the channels themselves since the channels are small anyways.
