These are looked at as infill at the moment with Pantographs for traction so Bi Mode.
A couple of issues with them is Range and method of charging if no electrification or EMU equipment.
This then leads into weight, between battery tech and the traction equipment these units are much heavier as you can imagine.
The most important factor is probably reliability, NR or TOCs and FOCs can't afford disruption with an already shakey reputation and coming off the back of the pandemic in bad shape and these units are not as reliable to date, will change with time I would imagine.
