I was wondering if there is any way to consolidate these multiple small amounts and turn them into one larger amount.
The hardest part is convincing someone to lend you a sizable amount. Then, consolidating your inputs without paying a fee is possible.
If that's all that were necessary, couldn't you just have the party with a sizable amount import your smaller wallet with multiple small inputs and sendmany the respective amounts to their 2 individual owners? Then the trust would be shifted to the party with the sizable amount of coins.
