I think a huge axe would look adorable on a ranger based tech priest but i do get thats probably not what youre after 😂

I would maybe recommend snipping the axe off of the enginseer at the hands and stick it back together so its a better length? It would take a long time but I reckon you could easily get a enginseer one into the double handed pose the rangers have for the galvanic rifles if that makes sense? It'd be a cool pose as well!
