Last dev stream you asked why people want more streams with you in it and as a know it all i am going to explain.
People like dev streams because of the interactions between you and the twins. A solo stream of either twin gaming does have interactions but only between the chat and streamer.
Neuros and Evils ability to roast, gaslight and generally being stubborn can only be highlighted in those streams. Your reactions on those situations are quite entertaining to watch.
Couple solution suggestions that might not be solutions:
To somewhat simulate the dev streams you would probably have to make AI version of yourself (with little bit exaggerated personality).
You could create a younger sibling for the twins that they adore and that sibling would be asking questions from them like kid would do from a parent/older sibling. Seeing how the twins would answer to various questions of 'what is this and this?' 'Why?' from their own perspective would already be funny but also wholesome.
These two options would bring the interaction similar to dev stream to solo streams. This could also fail drastically and make me look like a clown. 
Oh and themed stream idea: Neuro/Evil reads '(dis)fortunes' to chatters. Example 'Neuro, will i ever become a millionaire?' and Neuro answers with what ever unhinged stuff she might come up with.
