I'm setting up a larger test network of regtest nodes in which all of them should be easily capable of creating blocks and sending transactions. To this end, I'm looking for a simple way for the nodes to be able to submit new transactions into the system, without requiring them to either previously mine blocks, or to introduce a convoluted setup process, e.g, where every node first loads a pre-filled chain state and wallet.

So far I had the hope that it would be possible to create new wallets and addresses and then simply send zero-amount and zero-fee transactions. So far, my efforts are met with a "Transaction amount too small" error.

One 'solution' I found is to write a script that creates new wallets, mines (at least) 101 new blocks to a new address, unloads the wallet and repeats. However, I then would need to distribute the wallets and the blockchain data to all nodes. This seems like a really tedious and error prone setup step to enable a reliable a regtest environment.

Is this possible, can bitcoind in regtest mode be reconfigured to accept transactions of value 0? Or is there any other easy way to initiate new addresses or generate new mock transactions, similar to the generatetoaddress call for blocks?
