What are my options if I want to call an arbitrary function at an arbitrary address, from my wallet (Metamask)?

To be more precise, I want to be able to call a function from a web wallet, when I have the following ingredients:

  1. I know the contract address

  2. I know the function signature and know what parameters I want to use

  3. I don't have the full ABI

  4. The contract isn't verified in Etherscan, or something like that

Is my best option to write an interface, create a dumb website and connect my Metamask to it? Or to figure out the payload data and execute directly in Metamask? Aren't there some easier ways?

If the function name and parameters are known it should be possible to create a dummy contract and generate a minimal ABI with Remix. Then use Remix connected to Metamask or a wallet like MyEtherWallet and MyCrypto.
