Tbh I don't think this is more reasonable but we all have more to learn so I can't say it's impossible. Seems confusing contrived and slightly less intuitive to me though.
Is it? We all know matter can be converted to energy and vice-a versa. Many scientist would even go far enough to say that all we divide to matter and energy is really the effects of the fields involved. If we accept the EBH field then we accept virtual particles that interact to cause mass. So, even if the EBH field is just virtual particles, it has energy or it could not interact with itself or any mass. If it has energy it responds to gravity. So, then the EBH field is a good candidate for both dark energy and dark matter.
Further, to intuit that fields we understand cause dark energy and dark matter it not a big step. Energy is more likely shared between fields that not. What I express as an opinion does push the thought envelope a bit far but I think the pieces of the puzzle likely fit.
You seem to see no alternative to hydrinos or pico chemicals. I think we could easily find the truth. If we had time, money and could measure all the output chemical composition of BLP type experiments (especially gas products), we could see if there is transmutation or not. Until these measurement are make, I think there are answers to energy from BLP type experiments that are more reasonable, less confusing and certainly more in line with known science than hydrinos.
